Our S65B40 High-Performance Panel Filter is the ultimate first step for someone that wants to maintain and improve upon the highly engineered stock intake systems. This engineered filter is designed specifically for your BMW to deliver maximum airflow.

Maintaining proper CFM flow and particle capture efficiency is a delicate balancing act. Filters that flow well usually do not protect as well, and vice versa. Macht Schnell has mastered the formula to achieve this elusive perfect balance, so your engine assets will perform better without sacrificing protection.
