Active Autowerke BMW 528i Supercharger Kit E39

Active Autowerke E39 BMW 528i Supercharger System

Active Autowerke’s BMW 528i supercharger kit provides a much needed boost in horsepower to your E39 BMW 528i. 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 528i 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 BMW 528i supercharger system. This upgrade is a must for the enthusiast looking to kick up his car's performance a few notches.
