If you’re looking to give your BMW E9X M3 a little boost, this Active Autowerke water pump belt is a solid upgrade. It’s not just about the numbers—it’s about making your ride feel more alive. With gains of around 10 rear-wheel horsepower, and potentially over 12 compared to stock, you’ll notice the difference when you hit the gas.
Installation? It’s a breeze. This is a complete bolt-on system, which means you can easily swap it out without any hassle. Plus, if you ever want to revert back to the stock setup, you can do that too. It’s designed for both DCT and manual models, so no worries there.
What’s really cool is the material. Made from aircraft-grade billet 6061 aluminum with a hard coat anodized finish, it’s not just lightweight but also built to last. You won’t have to worry about it wearing out anytime soon. And hey, it even comes with replacement drive and A/C belts, plus an extra spare DPK belt if it's applicable for your setup. That’s a nice little bonus, right?
One of the standout features is how it reduces rotational mass without the overheating issues that can come with smaller pulley designs. This means you get more power without sacrificing reliability. Pair it up with AA software for even more gains, and you’ll really feel the difference.
So, if you're ready to take your M3 to the next level, this replacement water pump belt is a no-brainer. It’s a straightforward upgrade that delivers real results, and you’ll be glad you made the switch.
