Why do you need to upgrade the charge pipe on your N54 135i? The stock N54 charge pipe is a ticking time bomb for any 135i 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. 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 135i 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 135i there are two hookups for methanol or nitrous. To reconnect your factory TMAP sensor, there is a CNC-machined flange for perfect fitment.If you are looking to retain the OEM Diverter Valves, this version of the ARM N54 Charge Pipe is for you. It includes two ports to reconnect the OEM DV's and whether you plan to retain the OEM recirculation feature or vent to atmosphere, the ARM N54 Charge Pipe will do the job.
