Our rear diffuser for the FC1 Civic Si sedan.

  • 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!

Made from 5052 aluminum and comes powder-coated satin black. Includes all hardware needed to install, however adjustments may be needed on individual cars to optimize drag reduction.

Please note that this listing is a made to order item! Lead time should be from 4-8 weeks. We will contact you to confirm details before shipment.
