There are a lot of diffusers on the market but we like the factory CSL diffuser best. Unfortunately, the Genuine BMW part is unavailable without proof of CSL ownership. Luckily, this aftermarket diffuser is an exact replica. Made from carbon fiber, it fits in the rear bumper just like the real CSL part and looks identical. No CSL replica should be complete without this detail!
