Key Features:
Turn up the boost with a tune and find your $400.00 factory charge pipe break apart? You are not alone as this is a common situation with many enthusiast in this situation. The factory charge pipe is made out of plastic and was not designed to handle the higher boost levels. Well, fear not! The solution is here! Replace it with a higher flowing, stronger aluminum charge pipe! Made 100% of 6061 high grade aluminum, this will never happen again (backed by our Limited Lifetime Warranty)!
Often ignored, charged intake airflow characteristics greatly affect throttle response, turbo lag and ultimately maximum power potential. Smooth bends and minimal obstructions are ideal. We used 6061 aluminum (lightweight) mandrel bent piping to ensure smooth transitions. The upper pipe features 3" piping to match up to the factory throttle body (factory pipe is 2.5"), ensuring maximum flow without obstruction.
We were the first manufacturer to duplicate the factory throttle body flange with our N54 charge pipe. We bring the same thing to the N55 charge pipe. During our research and development, the connection at the throttle body was looked over very carefully. The factory charge pipe is connected to the throttle body using an o-ring inside the throttle body flange which is locked in place by a c-clip, which works very well. It also make removal/installation quick and easy. Our testing had shown it could hold quite a bit of boost. During our testing, we had pressure tested this connection up to 25 PSI. The reason why we stopped at 25 PSI was because at 25 PSI, one of the intake pipes on the turbo blew off and we could not test any higher. Hoewver, we were confident that it would easily hold over 25 PSI as the throttle body flange showed no signs of failing. Also, keep in mind, this type of connection is used throughout the engine, in many crutial areas like the coolant radiator system as well as the clutch system. If BMW did not believe in the durability of this type of connection, they would not use it in such important areas.
NOTE: This does fit the ActiveHybrid3 with the N55 motor.
