Active Autowerke set the tuning industry on fire by engineering the planet’s first proven supercharger system for the E46 M3. But some are you are flat-out hard to impress, so we felt compelled to raise the power bar even higher with a Level 2 solution that was un poco more aggressive – while still as refined and reliable as our standard kit.

Today, we’re up to Generation 3 of this dyno destroyer. And the numbers are hotter than ever. As in 525 BHP hot. And 0-60 in 4.1 hot.

Increased power output is achieved with a smaller 70 mm pulley (5 mm less than Level 1) and some very crafty software goosing. A supercooling Active Autowerke water/alcohol injection kit is added to help eliminate detonation or knocking. Keep in mind, this kit can push your BMW factory exhaust system beyond its power tolerance – Active Autowerke strongly recommends an upgrade to high flow performance headers and a top quality free-flowing rear exhaust system. Like the ones they make.
