N54 N55 Charge Pipe Upgrade Kit

The VRSF Charge Pipe Upgrade is engineered to replace the restrictive and failure-prone OEM plastic lower charge pipe found in BMW 135i, 335i, and 335is models with N54 or N55 engines. Constructed from mandrel-bent aluminum, this 2.5-inch piping increases flow, improves turbo spool, and allows for safer tuning for increased boost. The charge pipe features a CNC billet aluminum OEM throttle body flange for a secure, leak-free connection, and the entire assembly is finished in a durable, black powder coating. To enhance its utility, two 1/8" NPT bungs are included for users interested in methanol or water injection, complete with caps to cover intake re-circulation ports. All necessary couplers and clamps for installation are provided. This VRSF charge pipe is specifically designed for fitment with BMW E81, E82, E87, E88, E90, E92, and E93 chassis models equipped with the 3.0T I6 N54 or N55 engines.
