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.

Roof rails a proper fit for my Ford Transit Connect - SWB. Some concern about the threaded connectors, wondering if rivnuts might offer stronger attachment.

Customer photo review of NTXGlow RGB Tail Lights (2015-2023 Ford Mustang)

Took 2 weeks to deliver with standard shipping. But well worth the wait. Install took 25 minutes with minimal tools and the lights look amazing. Fitment is perfect and the quality is excellent. Its kinda pricey but you get what you pay for with ntxglow products. Highly recommend!

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 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.
