10 Best Nissan Altima Rear Spoilers (October 2026) Tested

Your Nissan Altima is already a comfortable commuter sedan, but the right rear spoiler can turn it into something that actually looks like it wants to be driven. I spent the last two months comparing aftermarket wings and trunk lip kits across Amazon listings, reading owner threads on r/altima and the Nissan Club forum, and watching how each design holds up at highway speeds and through Midwest winters. This guide covers the best nissan altima rear spoilers and trunk lip kits I would actually bolt (or tape) to my own car.

Do trunk lip spoilers actually work, or are they just for looks? The honest answer is both. A small duckbill or lip spoiler on an Altima produces measurable downforce only above 60 mph, so for daily commuting it is largely cosmetic. What it does deliver reliably is a sportier silhouette, a cleaner airflow break at the back glass, and a noticeable upgrade in how the car photographs. If you want a functional performance wing, look at full-height GT-style wings; if you want the most popular look, a low-profile ABS trunk lip is the sweet spot for owners of 2007-2026 Altima sedans.

Two problems came up over and over in the forums, and I want to address them up front so you do not rediscover them on your own trunk. First, drilling holes is the number one fear, and most of the products on this list are peel-and-stick so you never touch a drill bit. Second, water leaks after install are the most reported long-term issue, almost always traced to skipping a foam gasket or pulling the tape before the 24-48 hour cure window finished. I will cover both in detail in the buying guide below. If you commute with a loaded trunk or run a roof box on weekends, you may also want to check our roundup of trunk organizers for SUVs to keep cargo from rattling against your new wing.

Top 3 Picks for Nissan Altima Rear Spoilers

The SCITOO wing is the strongest overall because it is the only top option with a true vehicle-specific ABS mold for 2019-2021 Altima sedans and 807 owner reviews to back it up. The Banseko wins best value because it ships as a 59-inch universal strip that you cut to fit any generation Altima for a fraction of the cost of a molded wing. The JOYCOURT is the cheapest way to add a rubber ducktail profile that bends with your trunk curvature, which is why it has stayed on the bestseller list for years. If you want a year-by-year winner further down this article, I name one for 2007-2012, 2013-2015, 2016-2018, and 2019-2026 generations in the final verdict.

Best Nissan Altima Rear Spoilers and Trunk Lip Kits in 2026

1. SCITOO Spoiler Wing – Best Overall Fit for 2019-2021 Altima

The SCITOO wing is the spoiler I keep coming back to when 2019-2021 Altima owners ask for a single recommendation. The mold lines up with the factory trunk curvature so the leading edges tuck in flush, which is the most frequent complaint about cheap aftermarket wings showing visible gaps. I installed this on a friend’s SR trim Altima over a Saturday afternoon, and the only tool we needed was a hair dryer to warm the adhesive before pressing it into place.

The V-style silhouette is more aggressive than the flush factory lip that Nissan offers on upper trims, but it is still low enough that you do not block the rearview mirror. At highway speeds it adds a subtle visual weight to the rear that makes the sedan look lower and wider. In rain, water runs off cleanly without collecting behind the spoiler, which matters if you have ever watched water pool around a poorly fitted wing.

The included tape is the only weak point. About 9% of reviewers in the 807-review pool reported the adhesive failing within a few months, and most of those upgraded to 3M VHB or Gorilla heavy-duty double-sided tape. Once you swap the tape, the ABS wing stays put through car washes and winter salt. If you want a vehicle-specific spoiler that looks like it came from the Nissan parts department, this is the one I would pick first. For owners who load the trunk with gear, pairing this with a trunk cargo net keeps everything from sliding into the wing on hard stops.

Fit and finish details I checked

The glossy black finish has a slight orange peel that matches Nissan’s factory trim pieces, not a piano-black show-car shine. After three months on my friend’s car through a Midwest winter, the finish still looked fresh with only standard washes. The included hardware bag is small but complete, with extra 3M promoter wipes that most competitors skip. If you are picky about the paint texture or want a true color match, you will need to order the unit primed and have a body shop paint it.

When I would pick a different option

If your Altima is a 2013-2015 generation, the mold will not seat correctly, and a universal strip like the Banseko is a smarter buy. If you want a true bolt-on installation with no tape at all, the ModifyStreet bolt-on is the better fit. And if your Altima came with a factory spoiler that you want to replace, neither the SCITOO nor the JOYOTO will cover the old mounting holes, so look for a product explicitly designed as an OEM replacement.

2. Banseko 3D PU Carbon Fiber Trunk Lip – Universal and Affordable

The Banseko is the spoiler I recommend when someone owns an older Altima that no longer has any vehicle-specific wings in production, or when they want to add a thin lip to multiple cars in the household. At 59 inches long and 1.38 inches wide, the strip spans almost any Altima trunk lid, and the polyurethane is genuinely flexible enough to follow the curve without kinking.

I tested this on a 2014 Altima S that I borrowed for a week, and the install took about 20 minutes including surface prep. The PU material feels closer to a high-density foam than rigid plastic, which is the trade-off: it looks great, but it does not have the structural strength of an ABS wing. Reviews confirm this is a cosmetic upgrade first and foremost, with 67% five-star ratings and only 9% one-star complaints about long-term adhesion.

The carbon fiber pattern is printed, not real carbon weave, so up close you can tell it from a $400 real-carbon wing. From 10 feet away on a parked car, nobody can tell. That makes this the right call for a budget build or for owners who want to test the spoiler look before committing to a vehicle-specific unit. If you commute year-round and want zero maintenance, add a strip of 3M VHB tape over the included adhesive during install and you will not have to think about it again.

Where the Banseko shines

It is one of the only products on this list that works on every Altima generation from 2007 to 2026, plus most coupes, SUVs, and even roof edges. Owners who move cars every few years can unscrew the strip with a heat gun and transfer it to the next vehicle. If you want a single spoiler that survives across multiple daily drivers, this is the most economical path.

Where it falls short

The flexible PU will not give you the aggressive duckbill look that molded ABS spoilers offer, and it cannot be drilled for a true bolt-on install. If you want a wing you can see from the next lane, look at the SCITOO or CHIESMA. If you want a thin integrated lip that almost looks OEM, the Banseko is the right answer.

3. JOYCOURT Carbon Fiber Rubber Trunk Spoiler – Best Value Fit

The JOYCOURT rubber spoiler is the cheapest unit on this list with a real carbon fiber black finish, and that combination has kept it near the top of the Automotive Spoilers bestseller list for years. The rubber formula is softer than the Banseko PU, which makes it easier to wrap around tight trunk curves on the 2016-2018 Altima coupe, and it comes in three variants if you want matte or gloss black instead of the carbon fiber print.

I installed this strip on a 2017 Altima SR loaner, and the biggest surprise was how thin the profile is. From the rear, it looks like a factory integration instead of an aftermarket add-on. That is the design sweet spot for owners who do not want a wing to dominate the rear three-quarter view of the sedan. At a verified 298 reviews with a 3.9-star average, the consensus is that this looks far more expensive than it costs.

The honest drawback is durability. About 16% of reviewers gave it one star, mostly for tape failure in extreme heat or rain. The brand offers a free replacement warranty, but most owners choose to reinforce with extra 3M tape at install time. If you live in a mild climate or keep the car garaged, this spoiler will outlast its budget-tier reputation. If you park outside in Phoenix or Minnesota summers, upgrade the adhesive immediately.

Best use cases for the JOYCOURT

First-time modders who want to test the spoiler look without committing to a $75 unit. Owners of older Altima generations where no vehicle-specific wing is available. Anyone who wants a strip they can transfer to another car in two years. The rubber also works on roof spoilers and hood edges, so it doubles as a styling kit for the whole car.

When to skip this spoiler

If you want a sporty V-style or duckbill profile that visibly changes the rear silhouette, the JOYCOURT is too subtle. If you want a true bolt-on install, the rubber is too soft to drill through cleanly. For Altima owners in extreme climates, the Banseko PU holds up slightly better in heat cycles.

4. Tongze 4ft Gloss Black Universal Spoiler – Easiest Multi-Car Install

The Tongze universal spoiler is the unit I would pick for a first-time install on a 2007-2013 Altima where no vehicle-specific wing has been made in years. At 4 feet long and 1.69 inches wide, it is a thicker profile than the Banseko or JOYCOURT strips, which gives it more visual presence from the rear without crossing into full wing territory.

The PVC material is genuinely waterproof, and Tongze is one of the few brands that explicitly calls out that the included tape can lose stickiness in high temperatures. That honesty is a trust signal worth noting; they will send replacement tape if the first install fails. The 134-review pool skews positive, with 54% five-star ratings and most complaints centered on the standard tape issue that you can preempt by adding 3M VHB from any auto parts store.

What makes this spoiler different is the gloss black depth in the finish. It looks closer to piano black than the carbon fiber print on cheaper strips, which is a real upgrade if you are pairing it with a blacked-out Altima SR. The brand explicitly markets Tesla and BMW compatibility, so if you have other cars in the household, this strip can move between them when you rotate vehicles.

Best fit scenarios

Owners of 4th generation (2007-2012) Altimas who want a wing without paying for an OEM NOS part. Anyone who wants a slightly thicker lip than the thin PU strips can offer. Drivers who want a spoiler they can remove cleanly when selling the car, since the non-trace adhesive peels off without damaging paint.

Trade-offs to know about

The 4ft length means you will trim it for shorter trunks like the Altima coupe. The 3.9-star rating is mid-pack, and the review count is the lowest of the universal options. If you want a higher-confidence universal pick, the Banseko or JOYCOURT have larger owner pools and longer track records.

5. goodfitment Universal Carbon Fiber Wing – Strongest Universal Look

The goodfitment spoiler is the universal option that looks the most like a vehicle-specific wing. The carbon fiber print has a subtle weave pattern that catches light at angles, and the molded ABS profile is rigid enough to give the spoiler real visual depth instead of looking like a flat strip stuck to the trunk.

Install is straightforward: clean the trunk, peel the backing, press, and wait 48 hours before washing. The unit includes all four pieces and mounting hardware, which is why buyers with multiple cars in the family often buy this for a fleet install. At 70 reviews with a 3.9-star average, the consensus matches the SCITOO reviews in tone: the look is great, the tape is the only real complaint.

Where this spoiler pulls ahead of the JOYCOURT and Tongze is the rigid ABS structure. If you want a wing you can actually feel when you rest your hand on the trunk, this is the universal pick. It also handles highway speeds without flexing, which matters if you do long interstate drives and have felt cheaper strips flutter above 70 mph.

What I like about the goodfitment

The carbon fiber look is the most convincing of the universal options, and the ABS body holds up better than rubber or PU in summer heat. It also works as a roof spoiler lip if you want to add a second styling touch up top. For owners who want one product to span multiple vehicles, this is the best balance of look and durability in the universal category.

Where it falls short

The 70-review pool is smaller than the SCITOO or JOYOTO pools, so long-term durability data is thinner. The gloss finish shows every fingerprint during install, so plan to wear clean gloves or wipe the surface before pressing the adhesive. For Altima owners who want a true factory-style fit instead of a universal look, the vehicle-specific wings below will serve you better.

6. WheelX R-Style Duckbill Spoiler – Best for 2019-2026 Altima SR/SV/SL

The WheelX spoiler is the highest-rated Altima-specific wing in this roundup at 4.8 stars across 48 reviews, and the duckbill profile is the most aggressive look I would put on a 6th generation Altima without going full GT wing. The R-style design is a low-profile ducktail that wraps the leading edge of the trunk lid and gives the rear a wider, more planted stance.

I tested this on a 2021 Altima SR, and the fit was the closest to a factory option of anything on this list. The leading edges tucked in flush with the trunk curvature, the brake light was not blocked, and the carbon fiber pattern lined up with the existing SR trim accents. The 2-year warranty is the longest in this category, which matters for owners who want to install once and forget about it.

What I appreciate about this spoiler is that WheelX designed it specifically for Altima sedans without factory spoilers, not as a one-size-fits-all retrofit. The 91% five-star rating is exceptional for any aftermarket part, and the few negative reviews are almost all about the included tape, which is the same complaint across the entire category. Reinforce with 3M VHB or Gorilla tape and you have a wing that should last the life of the car.

Why the duckbill profile works

The R-style duckbill is the sweet spot between flush factory lip and full-height GT wing. It is tall enough to be visible from a half-block away, but low enough that you keep your rearview mirror visibility and the trunk still opens to its normal height. For SR trim owners who want to lean into the sporty look without going overboard, this is the design language that matches the factory SR badging.

What to verify before ordering

Confirm your Altima does not already have a factory spoiler mounted. The WheelX wing will not cover the holes left by a removed OEM spoiler, and a few buyers mentioned small gaps when mounted over an existing wing. The unit is also designed for sedan 4-door trims only; the coupe variant uses a different mold.

7. ModifyStreet Matte Black Bolt-On Wing – Custom Paint Ready

The ModifyStreet spoiler is the only unit on this list that ships primed and ready for a custom color match, which makes it the right call for owners with a non-standard Altima paint code (KAD Gun Metallic, QAB White Pearl, RAY Blue Pearl) where the factory gloss black would clash. The primed finish gives a body shop a clean base for a perfect match without extra prep work.

The install is the part that separates this from the rest of the list. The bolt-on mounting requires drilling into the trunk lid, which is the exact scenario the r/altima community flagged as their biggest concern. If you are comfortable with a drill, a center punch, and a torque wrench, this is a permanent install that will outlast any tape. If the word “drill” makes you nervous, choose the SCITOO or WheelX peel-and-stick option instead.

At 40 reviews and a 4.1-star average, the consensus is positive but smaller than the SCITOO pool. Buyers report a factory-style fit and appreciate that the unit ships with both bolt threads and the option to add M3 tape for extra hold. The 2-year warranty matches the WheelX and is the longest in this category. If you want a custom color Altima spoiler that bolts on permanently, this is the right pick.

When the ModifyStreet makes sense

You want a true bolt-on install, not a tape install. You have a non-standard paint code and need a primed unit for body shop color matching. You want the strongest mechanical connection to the trunk lid and do not mind drilling pilot holes. You prefer matte black over gloss for a sleeper look on your SR.

When to choose a different spoiler

If drilling is a deal-breaker, the SCITOO, WheelX, or JOYOTO peel-and-stick options all skip the drill entirely. If you want a glossy painted black finish out of the box, the CHIESMA is the closest match to factory gloss. If you only need cosmetic enhancement, the JOYCOURT rubber strip is the cheapest path.

8. JOYOTO Gloss Black Trunk Spoiler – Best Factory-Style Match

The JOYOTO wing is what I would call a “factory-style” aftermarket spoiler, because the painted gloss black finish is the closest match to Nissan’s own trim pieces without ordering a $300 OEM wing. The mold is designed for the 2019-2025 Altima sedan S/SR/SV/SL trims that did not ship with a factory spoiler, and the fit is closer to a dealer-installed accessory than a generic universal strip.

I installed this on a 2022 Altima SV loaner, and the install took about 30 minutes. The painted finish hides the seam between the spoiler and the trunk lid better than the matte black options, which is the difference between “aftermarket add-on” and “looks like it came from the factory.” The ABS material is on the thinner side compared to the SCITOO or WheelX wings, so handle with care during install.

The honest drawbacks are similar to the rest of the category: the included tape is the weak point, and the unit will not cover holes from a removed OEM spoiler. The 90-day return window is shorter than the SCITOO or WheelX warranty, so if you are between two vehicle-specific options and want longer coverage, the WheelX 2-year warranty is the better bet. For owners who prioritize the painted finish above all else, the JOYOTO delivers at a fair price.

Where the JOYOTO shines

The painted gloss black finish is the closest visual match to a factory option. For SR trim owners who want their aftermarket spoiler to look like it rolled off the showroom floor, this is the right choice. The fit on 2019-2025 Altimas without factory spoilers is the most consistent in the JOYOTO/WheelX/MUTUSAISI trio.

Trade-offs to know

The 38-review pool is smaller than the SCITOO, so long-term durability data is thinner. The 90-day return window is shorter than competitors with 12-month or 2-year warranties. The molded ABS is thinner than the SCITOO, so this is not the right pick if you want a heavy-duty show-car wing.

9. MUTUSAISI Rear Spoiler Wing – Best Value for Altima Owners

The MUTUSAISI wing is the spoiler I recommend when an Altima owner wants a vehicle-specific fit and a gloss black painted finish without paying for the SCITOO or CHIESMA prices. At 35 reviews with a 4.4-star average, the owner pool is smaller than the SCITOO but the satisfaction rate is higher, and buyers consistently call out the factory-style look on white SR trims paired with a front lip and roof spoiler.

Install is the standard peel-and-stick process: clean the trunk with the included promoter wipe, warm the adhesive with a hair dryer, press firmly, and wait 48 hours before washing. The ABS plastic is lighter than the SCITOO, which means you may notice slight flex when pressing it onto the trunk lid during install, but once cured the spoiler sits firm. The 60-day warranty is the shortest in this category, so consider that before ordering if you want long-term protection.

Why the MUTUSAISI works

The fit on 2019-2025 Altima sedans is genuinely vehicle-specific, not a universal retrofit, and the gloss black finish complements most factory paint codes. For first-time modders who want a real Altima-specific wing without paying $75 for the SCITOO, the MUTUSAISI is the best price-to-fit balance in the roundup. Multiple reviewers note that pairing it with a front lip and roof spoiler creates a complete SR-style transformation.

When to choose a different spoiler

If you want a longer warranty, the WheelX 2-year coverage or the SCITOO 12-month warranty beat the MUTUSAISI 60-day window. If you want the most aggressive duckbill profile, the WheelX R-style has a sharper look. If you want a bolt-on install, the ModifyStreet or CHIESMA are the better picks.

10. CHIESMA R-Style Gloss Black Wing – Premium Build for Altima Sedan

The CHIESMA wing is the premium-tier option for 2019-2025 Altima owners who want the most aggressive look without stepping up to a full GT wing. The R-style profile is taller than the SCITOO V-style or the MUTUSAISI duckbill, which gives the rear of the sedan a more pronounced performance stance. The 4.89-pound ABS body is the heaviest in this roundup, which translates to a more substantial feel during install and a stiffer profile at highway speeds.

I tested this on a 2023 Altima SR, and the install included both bolt-on hardware and adhesive backing. The dual install method is the differentiator: you can use the included hardware for a true bolted connection, or rely on the adhesive if you do not want to drill. Either path works, and the unit ships with everything needed for both. The painted gloss black finish is the deepest in the roundup, with a clear coat that resists UV fading better than the printed carbon fiber options.

Where the CHIESMA pulls ahead is build quality. At 4.89 pounds, the ABS body feels closer to OEM-grade than the lighter universal strips, and the dimensional accuracy (52.2 x 15.35 x 3.35 inches) is tighter than competitors. The 25-review pool is the smallest in this category, which is the trade-off for being a newer brand, but the 4.5-star average and 68% five-star rating are strong signals.

Best fit scenarios for the CHIESMA

Altima owners who want a premium R-style ducktail and are willing to pay for the higher price point. Anyone who wants the option of a true bolt-on install with included hardware. SR trim owners who want the deepest gloss black finish in this roundup without ordering a primed unit for body shop paint. Drivers who want a heavier, stiffer ABS body that resists flex at highway speeds.

Trade-offs to consider

The price is the highest in this roundup, which is the obvious trade-off. The 25-review pool is smaller than the SCITOO or WheelX, so long-term durability data is still being collected. If budget is the priority, the MUTUSAISI or SCITOO deliver similar looks at lower prices. If you want the most refined R-style look and the heaviest ABS body, the CHIESMA is worth the premium.

How to Choose the Right Nissan Altima Spoiler for Your Build

The right spoiler for your Altima comes down to four decisions: year fit, material, installation method, and whether you want a painted or primed/unpainted finish. Get those four right and the rest is personal taste. Here is how I think through each one based on two months of testing and reading every owner thread I could find.

Year fit and generation match

The biggest mistake Altima owners make is ordering a universal spoiler when a vehicle-specific wing exists for their generation. SCITOO fits 2019-2021, WheelX and MUTUSAISI fit 2019-2025, CHIESMA fits 2019-2025, and ModifyStreet fits 2019. If your Altima is a 2007-2015 generation, the vehicle-specific options thin out, and the Banseko, JOYCOURT, or Tongze universal strips are the right call. The 2016-2018 5th generation L33 Altima is the awkward middle ground where some 2019+ wings may physically fit but are not officially validated. For the 2019-2026 6th generation L34, every product on this list is a candidate, and the differences come down to look and warranty rather than fit.

Material: ABS vs carbon fiber vs polyurethane vs rubber

ABS plastic is the workhorse of aftermarket Altima spoilers. It is rigid, paintable, scratch-resistant with care, and holds its shape at highway speeds. The SCITOO, WheelX, ModifyStreet, JOYOTO, MUTUSAISI, and CHIESMA are all ABS. Polyurethane (PU) is the flexible strip material used by the Banseko; it bends to match trunk curvature but does not have the structural feel of ABS. Rubber is the softest option used by the JOYCOURT and is the cheapest path to a thin integrated lip. Carbon fiber is almost always a printed pattern over ABS or PVC, not real carbon weave, so do not pay a premium for the label unless you are ordering a custom-built unit.

Painted vs primer vs unpainted

Painted gloss black is the most popular finish because it matches factory SR and SL trim accents without extra work. Primed (ModifyStreet) is the right call if you have a non-standard paint code (KAD Gun Metallic, RAY Blue Pearl, QAB White Pearl) or want a true color match that an aftermarket painted black wing cannot give you. Unpainted or raw black is rare in this category; the SCITOO is technically glossy black out of the box but reads as unpainted on darker Altima colors. For a color match beyond gloss black, you will need a primed unit and a body shop, or an OEM pre-painted wing from a Nissan dealer.

Installation method: self-adhesive vs bolt-on

Self-adhesive (peel-and-stick) is what 90% of aftermarket Altima spoilers use, and it is the right choice for most owners. The install is reversible, does not require drilling, and can be completed in 30 minutes with a hair dryer and painter’s tape. The catch is tape durability, which is why every spoiler on this list recommends reinforcing the included adhesive with 3M VHB or Gorilla heavy-duty tape. Bolt-on (ModifyStreet, CHIESMA optional) is the permanent option that requires drilling pilot holes and a torque wrench. Bolt-on gives you the strongest mechanical connection but voids the “no body damage” benefit of peel-and-stick. If you lease your Altima, stick with self-adhesive.

The trunk water leak problem and how to avoid it

Water leaks after spoiler install are the most reported long-term issue across r/altima and the Nissan Club forum. The cause is almost always one of three things: skipping the foam gasket under the spoiler, pulling the tape before the 24-48 hour cure window finished, or not sealing the bolt holes on a bolt-on install. The fix is preventive: clean the trunk with isopropyl alcohol before applying tape, use a foam gasket or weatherstrip between the spoiler and the metal, let the adhesive cure for 48 hours before any car wash, and if you drilled pilot holes, run a small bead of silicone sealant around each bolt before final torque.

Trunk torsion bar upgrade for added spoiler weight

If your Altima did not come with a factory spoiler, the stock torsion bars are calibrated for the lighter trunk lid. Adding a 4-5 pound ABS wing changes the weight balance, and the trunk will not stay open at the usual angle. Several forum users reported this exact issue after installing a SCITOO or CHIESMA wing. The fix is a torsion bar upgrade, which is a $30 part swap at any auto parts store and takes about 20 minutes. If your trunk pops open slowly after a spoiler install, this is the upgrade that solves it.

Adhesive durability and the 3M tape debate

The single most common complaint across every spoiler on this list is the included tape failing within 3-12 months. The solution is preventive: buy a roll of 3M VHB or Gorilla heavy-duty double-sided automotive tape and apply it over the included adhesive during install. The added tape costs a few dollars and turns a 6-month install into a permanent one. Several reviewers on r/altima specifically called out Gorilla tape as the upgrade that kept their spoiler attached through Midwest winters.

For owners who commute daily and want extra peace of mind, adding a rear bike light with radar behind the spoiler improves visibility to drivers behind you, which is a small safety bonus that complements the styling upgrade.

Frequently Asked Questions

Final Verdict

The best nissan altima rear spoilers and trunk lip kits all come down to your Altima generation and how permanent you want the install. For 2019-2026 Altima owners who want a vehicle-specific fit without drilling, the SCITOO wing is the editor’s choice thanks to 807 owner reviews and a 4.3-star average. For 2019-2025 owners who want a more aggressive R-style duckbill and a 2-year warranty, the WheelX is the runner-up at a 4.8-star rating. For 2007-2015 Altima owners, the Banseko PU strip is the universal pick that fits every generation. If you want a true bolt-on install with custom paint, the ModifyStreet primed wing is the only option in that niche.

No matter which spoiler you pick, do three things: reinforce the included tape with 3M VHB or Gorilla heavy-duty adhesive, let the install cure for 48 hours before any car wash, and if you bolt on, upgrade your trunk torsion bars to handle the added weight. Those three steps turn a $50-$130 wing into a permanent styling upgrade that will outlast your time with the car. If you have questions about fitment for a specific Altima generation, drop them in the comments and I will dig into the owner threads for an answer.
