The way boosted intake airflow characteristics affect your vehicles throttle response, turbo spool, and the engines overall ability to make more power is usually something that gets overlooked. Clean bends, transitions and overall reduction of obstructions along the intake path make for more ideal pathway & efficient air utilization. The lightweight 6061 aluminum is mandrel bent to aid in smoothing out difficult transitions. By using 3" piping Evolution Racewerks was able to maximize the airflow through the throttle body with minimal obstruction.

Evolution Racewerks (E.R.) was the first manufacturer that chose to replicate the OEM throttle body flange on their original N54 charge pipes. For the N55 they have chosen to utilize the same tried and tested connection. The OEM flange which is locked in place by a c-clip and sealed with an O-ring is used in many vital places throughout the vehicle such as the clutch system and cooling system. While testing the charge pipes E.R pushed it up to 25 PSI. During their test one of the intake pipes on the turbo blew off so they could not continue to test any higher. The test showed it would easily hold over 25 PSI.

Other manufactures have choose to use silicone hoses where their pipes connect to the throttle body since it is cheaper to design than the proper flange and clip setup. The Problem though lies in the throttle body lip, which is much too short for a proper connection. And since there are no beads there is nothing to prevent the hoses from slipping off under boost. This is the reason Evolution Racewerks invested so much time and dedication in replicating the OEM style connection.

The MAP sensor also poised an issue with sealing properly. The OEM MAP sensor utilizes an o-ring on the sensor itself to seal against the flange on the factory pipe. While other have decided to use a whole hole in a silicone hose, with will most certainly create a boost leak Evolution Racewerks created a CNC MAP sensor flange that retains the same OEM style o-ring seal.
