To keep wind drag on the rear end of your E90 335i, HARD Motorsport has developed their lightweight Aluminum Rear Diffuser Kit. It reduces undercar drag, allowing for optimal downforce.

Diffuser is unpainted and does not work with stock exhaust. Straight pipes or custom exhaust work recommended.

Fits the following vehicles:

2006-2013 E90 BMW 335i 

The rear diffuser completes the look of the rear bumper and adds more presence and muscle to the aesthetics. The Akrapovic M2 rear diffuser is made from beautiful carbon fiber with a high gloss clearcoat. It fills in the gaps around the stock rear exhaust surround and is molded to fill the void between the exhaust tips.

While designed with the Akrapovic exhaust in mind, this M2 diffuser can be used with almost any stock or aftermarket exhaust.

Easy installation using stock hardware and reversible thanks to no modifications.

The Akrapovic Evolution and Slip-On line exhaust systems can be further enhanced with an optional hand-crafted carbon-fiber rear diffuser. Developed by Akrapovic’s Design Department, this stunning diffuser, crafted from materials developed through Akrapovic’s racing involvement, is designed to perfectly fit the lines of the unique tailpipes of the Slip-On or Evolution systems, as well as complement the sleek and sporty shape of the F90 M5 BMW.
