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.
