ER Charge Pipe for BMW N55 3.0T

BMW Performance Parts: ER Charge Pipe for BMW N55 3.0T (BM-ICP003)

Introducing ER's new Diverter Valve Charge Pipe for the BMW N55 Single Turbo Engine!  Fits all BMW 135i and 335i.

Often ignored, charged intake airflow characteristics greatly affect throttle response, turbo lag and ultimately maximum power potential.  Smooth bends and minimal obstructions are ideal. ER used 6061 aluminum (lightweight) mandrel bent piping to ensure smooth transitions.  3" piping was used to match up to the factory throttle body (factory pipe is 2.5"), ensuring maximum flow without obstruction.

ER was the first manufacturer to duplicate the factory throttle body flange with our N54 charge pipe.  They bring the same thing to the N55 charge pipe.  During their 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.  ER's testing had shown it could hold quite a bit of boost.  During their testing, ER had pressure tested this connection up to 25 PSI.  The reason why they stopped at 25 PSI was because at 25 PSI, one of the intake pipes on the turbo blew off and they could not test any higher.  Hoewver, ER was 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 ER's 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 they did.  ER spent a lot of resources developing and manufacturing this factory style connection for this reason.

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 ER CNC machined their own replica MAP sensor flange that utilizes the same factory o-ring seal.

1/8" NPT Bungs (For Methanol or Nitrous Injectors):

With the popularity of methanol injection systems and nitrous systems, ER has added the option of having a 1/8" NPT  threaded bung (for methanol or nos injectors) welded to our diverter valve charge pipe.  This allows quick and easy installation of methanol/nitrous injectors that are used in methanol injection systems and nitrous systems.  You have the option of adding 1 or 2 injector bungs.  Each 1/8" NPT bung will come with a plug so that you can run with or without the methanol injector.  This is perfect for those who do not have the Methanol Injection yet but plan to do so in the future.
