525 HP - New Heights Now Attainable (Gen 3Level II)
Active Autowerke is proud to introduce an upgraded kit for the BMW E46 M3 Supercharger.
Our Level II is just as reliable and refined as our standard kit, but provides more power suited for a more aggressive enthusiast. The increase in power output is achieved by using a smaller 70 mm pulley (Level I uses 75 mm) and slightly more aggressive software.
For added safety, an Active Autowerke custom Water Injection kit must be used as a precaution against detonation or knocking. In addition, the BMW factory exhaust system is not compatible with the increased power provided by this kit. High Performance Headers along with a high flow exhaust must be used to allow for a smoother and less restrictive flow of exhaust gases.
