Active Autowerke Gen 9 Level 2 Supercharger Kit

BMW E46 M3

When you thought it could not get any better, and after 10 yrs. of the #1 selling E46 SC Kit, Active Autowerke is proud to announce there new Generation 9 SC Kit.

Reliability and power are needed if you want to be on the podium, and this new Generation 9 will deliver exactly that. Consistent, repeatable runs of over 415 WHP (525 engine horsepower) were recorded from our Level 1 kit on the Active Autowerke Mustang chassis dyno in hot 94 + degree Fahrenheit conditions with humidity in the 60% + range.

The stage 2 System boosts the S54's power output to over 600BHP and includes an upgraded fuel system (includes two fuel pumps, fuel filter, all new -6 lines, fuel pressure regulator, dead end fuel rail, upgraded injectors and all required fittings). This ugpraded fuel system is a must once reaching these increased boost levels due to the fact that the factory fuel system is simply inadequate at this level. The stage 2 system also use a larger front mount air to air intercooler and our custom methonalanol injection system.


Due to the horsepower created, the factory headers may become clogged making the exhaust flow very restrictive.

To overcome this, the Active Autowerke headers with hi-flow metallic cats should be installed.
