Stillen Rear Diffusers

Not Yet Reviewed

Enhance the appearance, and aerodynamics, of your vehicle's rear-end with Stillen rear diffusers. Made from durable, lightweight polyurethane, styles are available unpainted--ready to prime and paint, or painted matte black and ready to install or paint. Each vehicle-specific diffuser is designed to complement the natural lines of the car, transforming it from boring to exciting. Most, but not all, models come pre-installed with 3M automotive tape and will not require cutting or modifications. Select the Stillen rear diffuser designed for your vehicle.
