Product Details

For vehicles with SMG transmission

As the producer of one of the finest working supercharger systems for the BMW E46 M3, Active Autowerke is proud to introduce the PRIMA PLUS supercharger system capable of exceeding 500 WHP running on pump drawn 93 octane. The PRIMA PLUS is an upgrade kit to the existing PRIMA supercharger system designed to create MORE horsepower.

In collaboration with Frank Smith of Tuning Tech FS, the Prima PLUS SC kit has evolved as a fantastic performer. With numerous dyno runs under countless hours all monitored through careful Data Logging and Lean/Rich evaluation, this PRIMA PLUS supercharger kit is ready for the BMW enthusiast.

The PRIMA PLUS is a centrifugal design supercharger using a conventional fixed drive pulley, but unlike its predecessors, the PRIMA PLUS also has variable boost settings of 9.0 psi and 9.5 psi to help attain the power. A first in the BMW forced induction industry. For easy comparisons, here is where the PRIMA and PRIMA PLUS + stands when measuring rear wheel horsepower. 

A stock BMW E46 M3 is around 265 WHP.  |  PRIMA SC makes 425 WHP. |  PRIMA PLUS SC makes 500+ WHP.
