Why upgrade the charge pipe on your N54 135i? The stock charge pipe is a ticking time bomb above stock boost — the plastic design holds on stock settings but is prone to bursting once tuned. This version of the ARM N54 Charge Pipe is built to retain your OEM diverter valves: it includes two ports to reconnect the OEM DVs, whether you keep the factory recirculation or vent to atmosphere. (Prefer a TiAL Q BOV? See the ARM N54 Charge Pipe with TiAL flange.)

Highlights

• Handles high boost.
• Dual methanol / nitrous bungs (pre-capped).
• Complete with hoses and hardware.
• Leak-free seal, 3" construction.

Construction

Machined from 6061 aluminum, connecting to the throttle body via a precision CNC connection secured by the OEM metal C-clip with an upgraded O-ring for a leak-free seal. Optimises airflow between the intercooler and throttle body, and includes a CNC-machined flange to reconnect the factory TMAP sensor. Fits the stock intercooler or any aftermarket unit that bolts to the stock charge pipe.
