Active Autowerke N55 Chargepipe Upgrade - E82 135i, E9X 335i

One major weak point in the N55 turbo plumbing is the stock upper chargepipe from the intercooler outlet to the intake manifold. The original N55 charge pipe is made from a weak plastic and can fail with even stock boost levels. The most common problem is a crack that develops along a seam where the pipe connects to the throttle body. Any crack here is bad as it creates a massive vacuum leak and the engine electronics will put the car into limp mode. If you don't want to be sidelined there is a very simple fix - the Active Autowerke N55 charge pipe.

This aluminum pipe is much stronger and more durable and nearly indestructable for the N55 application. It uses a CNC-machined factory-style connection and o-ring to the throttle body to ensure a tight and leak-free seal. The piping is a consistent 3" diameter for better flow and an improved throttle response. AA has included a raised boss with two ports should you choose to add a water/meth injection system later. The factory MAP sensor installs in the same location and the pipe is powdercoated black for a factory-type appearance.

With a stronger pipe you don't have to worry about the infamous chargepipe crack and lost boost levels and horsepower. All of the boost in the world is useless if it's leaking so using beefed up components in place of the weak factory pieces is the smart way to consistently high power output.
