Key Features
Functional design: Unlike many diffusers that just trap air inside the bumper, our design gently leads air out from under the subframe to reduce drag.
Clears most exhausts: The folded aluminum construction was chosen to optimize strength, cost, heat resistance, and exhaust clearance.
Durable mounting: Steel braces and brackets are designed to be strong but flexible — if you manage to bend the diffuser, all you need to do is bend it back!
