If you own an E46 BMW M3 and you're looking to kick your ride up a notch, the Active Autowerke PRIMA supercharger kit might just be what you're after. Developed alongside Frank Smith from TuningTechFS, this kit has made a name for itself as one of the best bang-for-your-buck supercharger systems out there. Trust me, it’s capable of pushing over 500 WHP with some easy Level 1 and Level 2 upgrades, which is pretty impressive for a car that’s been around since the mid-2000s.

What I love about the PRIMA system is its straightforward design. It’s a fully bolt-on, non-intercooled setup that doesn’t require any custom fabrication. So, if you’re like me and prefer to keep things simple, you’ll appreciate how easy it is to install. Plus, it’s completely reversible, meaning you can take it off without leaving a trace if you ever decide to go back to stock. And for those of you craving a little extra horsepower, the kit is totally upgradable—just a couple of tweaks and you’re on your way to more power.

Since BMW stopped making the E46 M3 back in June 2006, these cars have become a hot item for performance mods. The PRIMA supercharger is one of the more popular upgrades, with some folks reporting over 600 horsepower to the rear wheels. It’s a great time to jump into the supercharger game since the value of these cars is still relatively low compared to newer models.

Now, I’ll be honest—running this kit without an intercooler used to be a risky move, especially with the S54 engine’s high 11.5:1 compression. But thanks to years of testing and development, the PRIMA kit has been fine-tuned to work safely with the stock motor, so you can enjoy the boost without worrying about blowing your engine.
