Product Overview
A rear diffuser is usually replaced after curb damage, a cracked mounting point, or because the owner wants a more aggressive lower bumper without replacing the painted bumper cover. The integrated LED adds another system to check, so a light that stops working may be wiring-related even when the diffuser itself is fine.
This is an aftermarket styling piece and requires the LED to be wired into the vehicle's rear lighting circuits. Exhaust tip size, aftermarket exhausts, and non-stock bumper conversions can affect clearance, so test-fit the diffuser before drilling or making permanent electrical connections.

Frequently Asked Questions
