Co-developed with Frank Smith of TuningTechFS, the Active Autowerke PRIMA Supercharger Kit delivers a proven entry point into forced induction for the E46 M3. The system is engineered around efficiency, repeatability, and upgrade potential, with a baseline configuration that can grow beyond 500 WHP through available Level 1 and Level 2 packages. PRIMA focuses on clean, practical design. This is a fully bolt-on, non intercooled setup that installs without custom fabrication and can be reverted to stock if required. The modular architecture also allows straightforward progression to higher output configurations. As expected from Active Autowerke, the kit enhances overall performance while preserving the sharp throttle response and balanced character of the S54-powered M3.
