Included with the ARM S55 J Pipe are two pre-plugged1/8 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.
IN THE BOX
