Active Autowerke HKS

With 8 pounds of boost for an increase of over 100 flywheel HP, Active Autowerke’s 325i and 323i supercharger systems deliver instantaneous power and low end torque in amounts far beyond what the bimmer factory gods intended. With the new HKS GTS7040 compressor powering the system, your car reaches new heights with this upgrade.

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 car 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.

Bottom line: you get to experience near-M3 performance in your 325i or 323i at an incredibly affordable price. Without sacrificing drivability, comfort, integrity or amenities. Not too shabby at all.
