KXP Carbon Fiber Diffuser w/ Carbon Undertray - F80 M3 | F82 / F83 M4

This is the most aggressive rear diffuser we offer for the F80 M3 and F82/F83 M4; it is also our most popular product! Improving on the P Style diffuser, the KXP diffuser features an integrated 3rd brake light (modelled after an F1 rain light) which flashes when getting on and off of the brake pedal. The KXP diffuser gives any M3 or M4 an aggressive, aftermarket look that you just can't get with other diffusers on the market. Like all of our carbon fiber products, this one has an OEM-quality clear coat to protect against the harmful affects of UV rays. All 4 pieces feature a 2x2 carbon weave. Fitment is guaranteed on all of our carbon fiber products. Professional installation is highly recommended for this diffuser. This diffuser uses ALL OEM mounting points, no drilling necessary. Please note that we do recommend bolting the undertray to the diffuser to avoid unnecessary damage to the diffuser while driving. We recommend using OEM BMW 8MM female clips and screws for mounting.
