ARM Motorsports Charge Pipe For E8X/E9X BMW 135i/335i (N54)

Why do you need to upgrade the charge pipe on your N54 335i? The stock N54 charge pipe is a ticking time bomb for any 335i/xi 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 yours breaks to upgrade this critical component of your N54!

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.  For those of you looking to upgrade to a TiAL Q BOV, check out our N54 Charge Pipe with TiAL Flange.

Construction:

The ARM Motorsports N54 charge pipe is designed to handle the highest levels of boost. Constructed of 6061 aluminum, the ARM N54 335i charge pipe connects to the throttle body using a precision CNC machined connection which is secured by the OEM metal C-Clip.  It also includes an upgraded O-Ring for a secure and leak-free seal. 

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

OEM DV:

The ARM N54 OEM BOV Charge Pipe is engineered to optimize airflow between the intercooler and the throttle body.  To further increase the performance of your 335i, there are two hookups for either methanol or nitrous which come pre-capped. For reconnecting your factory TMAP sensor, there is a CNC machined flange for perfect fitment with new bolts to replace the course threaded factory screws.
