Pontiac G8 GXP Diffuser

The Pontiac GXP rear diffuser panel works beneficially in two ways. First, they evacuate high-pressure air under your vehicle to increase downforce. Secondly, they channel the air toward the back of the vehicle to reduce drag. This results in increased stability and cornering ability at high speeds, increased acceleration, and decreased fuel consumption. Rear diffuser panels are made of durable ABS material and serve as a direct replacement for your stock lower panel. This is the panel only, simply reuse your factory reflectors and hardware for installation.

If you need new clip fasteners, we have them available.  Holden Retaining Clip 92138627
