F3X N55 CHARGE PIPE - RWD

The F30 N55 charge pipe doesn't fall far from the tree of the E90 — it's plastic and prone to cracking, even on stock boost, leaving you in limp mode at the worst time. The risk only grows on tuned cars. The ARM F30 N55 RWD Charge Pipe removes that weak point with a build that handles the most demanding setups.

Highlights

• Built for high-boost applications.
• Mandrel-bent aluminum construction.
• CNC-machined throttle-body and intercooler connections.
• Meth / nitrous ready (1/8" NPT).
• Fits FMICs with OEM connections; fits both MT and AT.
• Complete with hoses and hardware.

Construction

Mandrel-bent T6061 aluminum for smooth transitions and minimal weld points, with CNC-machined throttle-body and intercooler connections for a precise, reliable seal. It begins at 3" at the throttle body and reduces to 2.5" to match the OEM intercooler, the ARM F30 FMIC, or any unit that connects to the stock charge pipe. Includes a CNC-machined MAP sensor flange, a 1/8" NPT port (meth/nitrous, boost tap or smoke testing), and a transmission vent connection for AT cars (capped for MT). Pair with the ARM N55 Turbo Outlet Pipe to fully upgrade the charge-air piping.
