If you're like me, you've probably spent countless hours dreaming about how to take your E46 M3 to the next level. Well, after a decade of refining their craft, Active Autowerke has rolled out the Generation 9 Supercharger Kit, and let me tell you, it’s a game changer.

This isn’t just another shiny product; it’s built on years of experience and feedback from real drivers. With this kit, you’re looking at a solid 415 WHP—yeah, that’s 525 horsepower at the crank—recorded on their Mustang chassis dyno, even in sweltering conditions of 94°F with humidity cranked up to 60%. If it can handle that, imagine how it’ll perform on a cooler day when the air is denser. It’s all about reliability and power, and this setup delivers both in spades.

So, what’s in the box? You’ve got a Rotrex 92 Trim Supercharger at the heart of it, which is known for its high adiabatic efficiency. That means you’re not just getting power; you’re getting it efficiently. The kit also features the Active Autowerke Generation 7 Intake Manifold equipped with a dual bypass valve, which helps keep everything running smoothly. And let’s not forget the front mount air-to-air intercooler that keeps those intake temps down, allowing for better performance.

Fuel delivery is crucial when you’re pushing these kinds of numbers, so Active Autowerke has included larger fuel injectors and even a supercharger oil cooler to keep everything in check. Plus, you’ll want to pair this with a proper BMW M3 Signature Exhaust to really unleash the beast.

Here’s the skinny on the performance specs: you’re looking at 525 BHP at 7650 rpm and torque figures hitting 335 ft/lbs at 5400 rpm, all with a boost level of 7-8 psi. That’s some serious grunt for your M3.

Oh, and don’t sweat the installation; the kit comes with all the mounting hardware, plumbing, hoses, and clamps you’ll need, plus detailed instructions to guide you through the process. Just a heads up, though—these supercharger kits can take up to six weeks to ship due to blower availability, so it’s a good idea to call ahead and confirm.

All in all, if you’re ready to take your E46 M3 from a great car to an absolute monster, the Active Autowerke Generation 9 Supercharger Kit is the way to go. And with a 2-year limited warranty, you can hit the road with confidence.
