No one buys a BMW M3 because they like limits. Here at Active Autowerke, we know that well.

This carefully engineered BMW M3 Supercharger kit matches the Rotrex C38 supercharger with the perfect hardware, software and tuning to take the factory 240 HP straight up to over 400 HP - 350 HP at the wheels (with the potential for even more power with our ultimate Level 3 kit).

The level 2 version of this BMW M3 Supercharger system brings you car to another level, boasting a large front mount air to air intercooler and comes complete with all piping and hardware required to make this bolt on application work. This upgrade increases your car HP an additional 25-50HP over the stage 1 system. The stage 2 upgrade also includes an new high performance fuel pump to help deliver the necessary fuel. With the reliability and performance of an intercooled system along with our perfectly tuned software this system is a must for the true enthusiast looking to bring their M3 to new heights.
