If you’re pushing your BMW N55 engine to its limits, you know the factory charge pipe can be a weak link. That’s where the Evolution Racewerks Charge Pipe comes in. Unlike other brands that cut corners with silicone hose connections, Evolution Racewerks has crafted a solid solution that’s designed to last. The factory setup has a throttle body lip that's just too short and lacks the necessary beads to keep silicone hoses in place under boost. Trust me, you don’t want to be dealing with blown hoses when you’re trying to enjoy the ride.

So, what makes this charge pipe a game-changer? For starters, it’s made from 100% 6061 high-grade aluminum, which means it’s not just stronger but also lighter than the factory plastic. You’ll notice the difference in throttle response right away—less turbo lag and more power on tap. The upper pipe features a 3” diameter to match the factory throttle body, compared to the stock 2.5”, allowing for maximum airflow without any nasty obstructions. Evolution Racewerks didn’t just slap this together; they meticulously designed it to replicate the factory throttle body flange, which is a big deal. This ensures a secure connection without the hassle of silicone hoses that can lead to leaks.

Installation is a breeze, thanks to the precision CNC machined throttle body flange that retains the factory-style O-ring lock. This design not only makes it easy to connect and disconnect but also holds up under pressure—Evolution Racewerks tested it up to 25 PSI without any signs of failure. They even had to stop testing because one of the intake pipes blew off before they could push it further. That’s confidence in durability!

And let’s not forget about the MAP sensor. Evolution Racewerks made sure to include a CNC machined MAP sensor flange that utilizes the same factory O-ring seal. This is crucial because any hole in a silicone hose can lead to a boost leak, which is the last thing you want when you’re trying to maximize performance.

This kit comes with both the upper and lower charge pipes, so you’re fully equipped for installation. Plus, it features beaded ends and T-bolt clamps that keep everything secure, even when the boost kicks in. A silicone hump hose is included, and it’s compatible with the factory electronic diverter valve, making it a seamless upgrade.
