High-Performance Engine Upgrades for N54, N55, and S65

The engine bay of the BMW E9X and E8X platforms is a masterpiece, but it has its weaknesses. Heat management is the biggest enemy of the N54 and N55 engines. Our collection focuses on "preventative performance." From billet oil filter caps that dissipate heat to the famous Bevinsee cowl filters that improve airflow and cabin air quality. If you are pushing more boost, our engine harness brackets and aluminum upgrades are essential to keep your build reliable on the street and the track.
