Installation

This diffuser is a direct replacement for the factory unit — the original diffuser is removed and this carbon assembly installs in its place. Expect approximately 2–4 hours including removal and alignment, using specialized tools for bumper panel access and fastener removal. This is an advanced install — professional installation is strongly recommended for correct alignment and finish protection.

Before You Install

Please inspect the diffuser and confirm the carbon weave, finish, and fitment before installation. If you have a fitment question, contact us with your year and model and we'll help confirm compatibility.
