Active Autowerke’s 330i supercharger kit delivers instantaneous power and low end torque in amounts far beyond what the bimmer factory gods intended. Specifically designed to run with 91-93 octane pump fuel and your stock engine management system, this system uses our dyno-tuned software adjustments to manage ignition, fuel, vanos, rev limits, speed governors, etc – all programmed into the same onboard computer your 330i was born with. So the performance mutation from normal to ‘extra-assertive’ is smooth and dependable, and totally reversible to stock. Even our oil cooling upgrade is self contained and non-intrusive of the factory oil system. Nothing beats a complete bolt on supercharger system. Bottom line: you get to experience M3 performance in a 330i at an incredibly affordable price. No need to sacrificing drivability, comfort, integrity or amenities that you have grown to love. That’s an evolution worth pursuing.
