MMR Performance have developed an Elite Series of direct replacement foam panel filters for the BMW N55, manufactured using some of the same techniques and materials as seen in Formula 1, World Rally and Touring Cars. 

These design skills, the advanced technology and attention to detail are also all used to produce our Elite Series of high grade replacement filters for both road and competition use.

This is a direct replacement filter for your OEM air filter, and does not need replacing at service intervals.
