2012+ N55 (3.0T) F30/F32/F33/F20/F21 A/T Charge Pipes for X-DRIVE ONLY AWD (Polished)
Charge Pipe for the 2012+ BMW 335i N55 Single Turbo Engine, 2013+ BMW 435i N55 Single Turbo Engine and 2012+ BMW M135i N55 Single Turbo Engine with AUTOMATIC Transmission.
IMPORTANT: THIS ITEM IS INTENDED FOR RACE OR COMPETITION USE ONLY
Turn up the boost with a tune and find your factory charge pipe break apart? 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.
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.
Precision CNC machined throttle body flange ensures boost leak free connection
Many competitors use a silicone hose connection for the throttle body connection. It is not designed for a silicone hose connection which is used by all the other brand diverter valve pipe upgrades in the market. The throttle body lip is too short and there are no "beads" to prevent the silicone hose from blowing off under boost. Even though it is the easiest way to "rig" together, it is not ideal. The best way to connect the new diverter valve pipe to the throttle body is to replicate the same connection.
Precision CNC Machined MAP Sensor Flange and Vacuum Fitting ensures boost leak free connection
The same issue came with the MAP sensor. The MAP sensor seals to the factory diverter valve pipe via a o-ring on the sensor itself. Having a hole in a silicone hose will definitely cause a boost leak as it will not properly seal. Therefore, again we CNC machined our own replica MAP sensor flange that utilizes the same factory o-ring seal.
The charge pipe kit for the F30 N55 engine features two charge pipes, the upper and lower charge pipes. Both charge pipes are included in the kit and are required for installation.
