Why upgrade the charge pipe on your 135i? The OEM BMW charge pipe is a ticking time bomb for any N55 running above stock boost — the plastic design holds on stock settings, but failure is inevitable once tuned. Don't wait until you're limping home to replace this critical component. The ARM N55 Charge Pipe is machined from 6061 aluminum to handle the highest boost levels, with a precision CNC throttle-body connection secured by the OEM metal C-clip and an upgraded O-ring for a leak-free seal. Highlights Handles high boost. Dual methanol / nitrous bungs (pre-capped). Complete with hoses and hardware. Leak-free seal, 3" construction. Construction Optimises airflow between the intercooler and throttle body. Includes a CNC-machined flange to reconnect the factory TMAP sensor with new bolts. Fits the stock intercooler or any aftermarket unit that bolts to the stock charge pipe. Fitment (N55 3.0L) BMW E82 135i, E88 135i, E90 335i & 335xi, E92 335i & 335xi, E93 335i.
