If you're looking to take your BMW E46 M3 to the next level, the PRIMA PLUS supercharger system from Active Autowerke is worth your attention. This isn’t just another aftermarket part; it’s a serious upgrade that can push your ride to over 500 WHP on good ol' 93 octane. Yeah, you heard that right—500+ horsepower just waiting to be unleashed.

What sets the PRIMA PLUS apart from its predecessor, the original PRIMA supercharger system? Well, for starters, it’s been fine-tuned in collaboration with Frank Smith from Tuning Tech FS, and let me tell you, this thing has been through the wringer on the dyno. Countless hours of data logging and testing have gone into perfecting this kit, ensuring that it’s not just about numbers but real-world performance.

This supercharger features a centrifugal design with a fixed drive pulley, but it’s got a trick up its sleeve: variable boost settings at 9.0 psi and 9.5 psi. This means you can dial in the power you need for whatever driving situation you find yourself in. Whether you’re hitting the track or just cruising around town, you’re going to feel the difference.

Now, let’s talk numbers. A stock E46 M3 is around 265 WHP, and with the original PRIMA, you’re looking at about 425 WHP. But with the PRIMA PLUS? You’re stepping into the realm of 500+ WHP. That’s a serious bump in power, and it’s all thanks to the meticulous engineering that’s gone into this kit.

Features That Matter:

• Complete Water/Methanol system to keep things cool and efficient.
• Trunk-mounted WA tank that won’t eat up your cargo space (unless you’ve got a convertible).
• WA pump with internal seals and nozzles that can handle methanol like a champ.
• Integrated wiring that includes fail-safe features—safety first, right?
• Precise software tuning to match the boost levels you choose.
• All of this runs smoothly on 93 pump octane.
