So, you've got a 2011 BMW 135i or 335i with that N55 engine? You might have noticed that the factory charge pipe isn’t exactly built to last. Seriously, it’s made of plastic, and we all know how that story ends—eventually, it’s going to crack at the seams. When that happens, you’re looking at a vacuum leak that’ll throw your engine into limp mode. Not fun, right? Your ride starts feeling sluggish, like it’s missing a beat.
Enter the Active Autowerke N55 Charge Pipe. This isn’t just some generic upgrade; it’s specifically designed to tackle the issues that N55 owners face. Made from sturdy aluminum, this charge pipe is built to withstand the test of time. Say goodbye to those annoying plastic failures. The CNC-machined throttle body connection means it fits like a glove, ensuring a tight seal that won’t let you down.
Now, let’s talk size. This bad boy sports a consistent 3.00-inch diameter throughout, which means no restrictions and a smoother airflow. You’ll notice the difference in throttle response—no more annoying lag, just pure driving enjoyment. Plus, it keeps the factory O-ring seal to make sure everything stays snug.
If you’re into pushing your N55 engine further, you might be considering water/methanol injection. The cool thing about this charge pipe is it comes with provisions for two water/methanol nozzles. There’s a raised boss upstream that allows for proper atomization before the mix hits the engine. We even checked the thread depths to make sure the spray pattern is spot on—no awkward hits against the walls of the threaded holes.
Just a heads up, the factory throttle clip isn’t included with this charge pipe, so you might want to grab one if you don’t have it handy.

If you’re ready to ditch that flimsy factory charge pipe and give your BMW the upgrade it deserves, this is it. Trust me, your engine will thank you.
