Active Autowerke's 328i supercharger kit provides a much needed boost in horsepower to your E46 328. Specifically designed to run with 91-93 octane pump fuel and your factory ECU, this system uses our dyno-tuned software adjustments to manage ignition, fuel, vanos, rev limits, etc all programmed into the same onboard computer your 328i 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 328i at an incredibly affordable price. This is a must for the true E46 enthusiast.
