Why do you need to upgrade the N54 charge pipe for your 335i? The OEM BMW charge pipe is a ticking time bomb for any N54 335i running higher than stock boost. Its plastic design will adequately hold the boost on stock settings, but on tuned cars it is prone to bursting. In addition, the OEM diverter valves are another component not designed for upgraded tuning, as they will leak precious boost reducing the power your 335i can put down. Don’t wait until your driving home in limp mode to upgrade this critical component!

The ARM Motorsports N54 charge pipe is designed to handle the highest levels of boost. Constructed of space-grade 6061 aluminum, the ARM N54 335i charge pipe connects to the throttle body using a connection similar to the OEM design with C-Clip but much stronger, and includes an upgraded O-Ring for a precise and secure fitment.

It is engineered to optimize airflow between the intercooler and the throttle body, and to further increase the performance of your 335i/xi there are two hookups for methanol or nitrous. To reconnect your factory TMAP sensor, there is a CNC-machined flange for perfect fitment.

The integrated blow-off valve flange is designed for any 50mm TiAL BOV (BOV not Included). Most importantly, it will ensure that all of your boost makes it into the engine to maximize power output from your 335i/xi.

The design of this charge pipe will fit the stock intercooler or any aftermarket intercooler that bolts up to the stock charge pipe.
