Active Autowerke Supercharger Rotrex C38 Gen 9.5 Intercooled Kit for BMW E46 M3 2001-2006
$10687.00

If you're looking to take your E46 M3 to the next level, you’ve got to check out the new Generation 9.5 Supercharger Kit from Active Autowerke. After a solid decade of perfecting their E46 M3 SC kit, they haven’t just rested on their laurels; they’ve gone back to the drawing board and come up with something that’s truly impressive.

What’s great about this kit is that it’s all about reliability and power—two things you definitely want if you’re aiming for podium finishes. During testing, we saw consistent, repeatable runs of over 415 WHP, which translates to about 525 horsepower at the engine. And that was in some pretty tough conditions—think 94°F with humidity hanging around 60%. If it can perform like that in the heat, you know it’s only going to get better as the weather cools down and the air gets denser.

One thing I can't stress enough is the importance of pairing this supercharger with a proper BMW M3 Signature Exhaust. It really helps maximize the power output, making sure you get the most bang for your buck.

Here’s what you can expect from the kit:

  • Rotrex 92 Trim Supercharger that’s got some serious torque.
  • High Adiabatic Efficiency—basically, it keeps the power coming without overheating.
  • Active Autowerke’s Generation 7 Intake Manifold with a Dual By Pass Valve, ensuring smooth airflow.
  • A robust Front Mount Air to Air Intercooler to keep things cool under pressure.
  • Larger Fuel Injectors for that extra kick when you need it.
  • A Supercharger Oil Cooler to keep everything running smoothly.
  • Colder Heat Range Spark Plugs for better ignition.
  • A High Performance AA Spec Green Filter for optimal air intake.
  • Active Autowerke’s High Performance Software to tie it all together.
  • All the mounting hardware, plumbing, hoses, and clamps you’ll need to get it set up.
  • Proven horsepower gains, even under extreme conditions.
  • Comes with installation instructions—so you can tackle it yourself if you’re up for it.
  • A 2-Year Limited Warranty for peace of mind.

Performance Specs:

  • Power: 525 BHP @ 7650 rpm
  • Torque: 335 ft/lbs @ 5400 rpm
  • Boost Level: 7-8 psi

Fitment:

  • BMW E46 M3 from 2001 to 2006

Notes:

  • Keep in mind that all supercharger kits may take up to 6 weeks to ship due to blower availability. It’s a good idea to call ahead to confirm.

So, if you’re ready to unleash the true potential of your BMW E46 M3, this Active Autowerke Supercharger Kit is worth considering. It’s built for enthusiasts who want to feel that rush of power every time they hit the gas.
