Why do you need a charge pipe for your 135i? The OEM BMW charge pipe is a ticking time bomb for any N55 135i running higher than stock boost. Its plastic design will adequately hold the boost on stock settings, but on tuned cars its failure is inevitable.  Don't wait until your driving home in limp mode to upgrade this critical component of your N55!
 The ARM Motorsports N55 charge pipe is designed to handle the highest levels of boost. Constructed of 6061 aluminum, the ARM N55 135i 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 ARM N55 Charge Pipe is engineered to optimize airflow between the intercooler and the throttle body.  To further increase the performance of your 135i, 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.
 
 
The design of this charge pipe will fit the stock intercooler or any aftermarket intercooler that bolts up to the stock charge pipe.
