PROFILE
Complete your S55 upgraded charge piping with the ARM S55 J Pipe! 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 with only one methanol port are not able to supply a sufficient amount of methanol for advancing the timing enough to make any substantial power increases.
For reinstalling your S55 vacuum line, the ARM J Pipe has a precisely machined vacuum line connection port to prevent any leaks, a common issue on many other S55 J Pipes.
