The stock intake pipe has several glaring weak spots which require attention before any modifications. The cp-e 135i/335i/535i N54 intake charge pipe is stronger, more durable, and much higher quality than the disappointing stock plastic part. The cp-e N54 chargepipe is made with anodized aluminum and a CNC-machined connector flange to the throttle body. The stock part has the potential for failure in multiple places - along the body of the pipe, the necks for the original boost diverter valves, and at the connection to the throttle body. A hole or crack at any one of these spots will allow charged intake air to escape into the engine bay instead of making it into the engine. What good is any turbo upgrade if the forced air never makes it into the engine? The cp-e N54 chargepipe is stronger and better manufactured to eliminate boost leaks as a problem.

All connection pieces are included for a seamless install. However, we do strongly recommend upgrading the throttle body c-clip at the same time. This pipe works with the diverter valves in the stock recirculation system. Upgraded diverter valves are also recommended. An additional bung is installed for connecting methanol injection. Other chargepipes are also available to eliminate the diverter valves and use a traditional blow-off valve.
