This J Pipe is the final piece of piping on the S55 before the charge air enters the intake manifold. BMW constructed the OEM J Pipe of plastic which is prone to cracking an detaching from the throttle body under boost.The ARM S55 J Pipe is constructed of T6061 aluminum for a durable replacement that will hold up to even the most demanding builds. The ARM S55 J Pipe is designed to lock onto the stock throttle body using a CNC machined connector. This connector incorporates a locking C-clip design which replaces BMW's one-time use plastic strip to create a secure connection to the throttle body.Included with the ARM S55 J Pipe are two pre-plugged 1/8 NPT fittings which allows for post-intercooler methanol or nitrous injection. This is the preferred location of injection for many S55 tuners. J-Pipes w
