FAQs

Will this require a tune after installation?

Bolt-ons like exhaust tips, cat-backs, and basic intakes usually don't. Larger mods — turbo upgrades, supercharger kits, headers — typically need an ECU tune to run safely. The spec sheet indicates if tuning is recommended.

Is this part emissions / CARB compliant?

If you're in California or another CARB-regulated state, check the CARB status on this page before ordering. Many performance parts are off-road or competition use only — if so, we say it clearly.

Will installing this void my factory warranty?

Modifications can affect manufacturer warranty on related components only — not your entire warranty. The Magnuson-Moss Warranty Act protects you from blanket warranty voids. If warranty matters to you, talk to your dealer before installing.

Can I install this myself?

Depends on the part. Bolt-ons are DIY-friendly. Turbo upgrades, headers, and supercharger kits need a professional shop. The product description gives a difficulty estimate.

Customer photo review of Spec-D Projector Headlights Ford F150 (04-08) Mark LT (06-08) Halo Black / Smoked / Chrome

They look amazing, and after using ChatGPT to help me understand how to install them (because the instructions were not very helpful whatsoever), I’m glad with how they turned out. My problems are that the lights aren’t too bright, the instructions weren’t helpful, and the arrival date was wrong, even if they arrived early.

Customer photo review of 2015-2021 Subaru WRX NBR Concept Style Trunk - Carbon Fiber

Unfortunately was damaged in transit. I was so excited I discarded the box and stuff without a thought and only took pictures of the damaged parts as I unboxed it. Seller needs pictures of the shipping label and box as well for any claims/partial refunds. The UPS guy that dropped it off didn't require me to sign for it like it said, just left it at my door. FYI for anyone buying something like this take pictures of EVERYTHING. I installed the trunk anyways cause I already had my trunk off. Decent fitment, no issues closing or opening the trunk but the trunk noticeably sits a little higher than the rear fenders.

Customer photo review of Front OEM Cover Overlays - *2024+ Tacoma / *2025+ 4Runner

This sticker sucks! Nice looking until you try to install it. Other stickers I have purchased come with a cover OVER the sticker. Peel the sticker and cover off the backing. Position the sticker over the object and press on. Usually includes a tool to make sure the sticker is firmly installed. Peel off the cover and done. No wrinkles. Not so with your product. No cover. No way to remove the backing while installing. A wrinkled mess.

Customer photo review of 1993-1997 Honda Del Sol Redclear Tail Light Lenses

This isn’t on K2, but the lenses came In which I was thrilled about. I’d already removed my OEM lenses from their housings. The passenger side lense fit well and mostly flush. The driver side, however, looks like it was slightly warped and caused poor fitment and what looks like a small dip in the red portion of the lense. I had no choice but to use them, as my OEM lenses were no longer usable. It can be very difficult to get replacement lenses in a timely manner for a Del Sol. I drive my car everyday, so I had to just go with it. Again, not a K2 issue but presumably the manufacturer.

Customer video review of 2003-2008 Nissan 350Z N4 Style Rear Bumper Cover - FRP

This rear bumper fits great the only thing is the trunk button on the bottom is cut a little to wide but that’s an easy fix it looks great and definitely makes the rear look more aggressive. I love it!

Customer photo review of Upgraded VANOS Oil Supply Line – M52 / M54 Engines (E36, E46, E39, E60, X3, X5, Z3, Z4)

The box was a little crushed, but the line was packed well and it wasn't a problem. The instructions are 3 pages of color pictures and lots of explanations. Very nice. The line itself is a very nice bit of kit with a swivel AN line end that allows a No-tension install. No leaks so far and it looks great. It came with new banjo bolts and copper crush washers. The only criticism I have is that I would have liked this hose coated in black so it disappears like the original, but it does look good, so I don't mind.

No damages on the product, and better return policy, I tried to get an exchange and they were charging me a %25 restocking fee when my product was damaged and dented, the communication on the matter was taking about 2 weeks as well.

Roundels showed up good quality and fit perfect. Also, anyone with a G22 who cant find anything for the rear, after emailing to ask them I was told they could custom do the 100mm rear roundel with camera hole cut out but just didn't have it listed. Charged me same cost, mailed it out same day. Highly satisfied!

Customer photo review of TESERY 19" /20" Wheel Brake Caliper Cover For Tesla Model Y 2020-2026

It took a month to get my product once I ordered and paid for it, which was not something I anticipated. There were no instructions whatsoever included in the package, which I found frustrating. The product was exactly as advertised, and I am satisfied with what I purchased. I will be more careful from who I purchased with in the future to make sure I’m not waiting for the slow boat from China.
