Since one of the reasons for changing out the factory diverter valves was to prevent boost leaks (from prematurely opening on high boost), causing boost leaks while upgrading the diverter valve would be counterproductive. During Evolution Racewerks research and development, the connection at the throttle body was looked over very carefully. The factory diverter valve 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. Evolution Racewerks testing had shown it could hold quite a bit of boost. During Evolution Racewerks testing, Evolution Racewerks had pressure tested this connection up to 25 PSI. The reason why Evolution Racewerks stopped at 25 PSI was because at 25 PSI, one of the intake pipes on the turbo blew off and Evolution Racewerks could not test any higher. Hoewver, Evolution Racewerks 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.
Many of Evolution Racewerks 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 which Evolution Racewerks did. Evolution Racewerks spent a lot of resources developing and manufacturing this factory style connection for this reason. Precision CNC machined throttle body flange ensures boost leak free connection.
