The VRSF charge pipe kit replaces the plastic OEM charge pipe on 2012–2017 BMW N55 cars: M2, M135i, M235i, 335i, 435i and ActiveHybrid3. It is mandrel-bent T6061 aluminum with CNC billet flanges at the throttle body, intercooler and vacuum connections, TIG welded and jig-tested for fitment, finished in wrinkle black powdercoat. It includes 4-ply silicone couplers, stainless T-bolt clamps and a plugged 1/8-inch NPT bung for methanol injection or a boost source. The main draw is durability: the stock plastic pipe is known to crack at stock and tuned boost levels, and this kit is the common fix.

Owners fit this kit mainly to replace a cracked stock pipe. They report solid fitment, no boost leaks and a more direct throttle feel, with the usual complaints about tight installs and the separate c-clip.
The VRSF Charge Pipe Upgrade Kit replaces the factory charge pipe on N55-powered F-chassis BMWs. It is designed to increase throttle response and decrease turbo lag. The kit also fits the ActiveHybrid3.
Each pipe is made from T6061 mandrel-bent aluminum, with CNC billet aluminum flanges for the throttle body, intercooler and vacuum connections. The parts are TIG welded and hand finished, then tested on multiple jigs to check fitment and a leak-free connection. The finish is a durable wrinkle black powder coat.
The kit includes one plugged 1/8" NPT bung, which can be used for methanol injection, boost leak testing or as a boost source. It also comes with 4-ply silicone couplers and stainless steel T-bolt clamps, so it has everything needed to replace the factory charge pipe. Replacement throttle body C-clips and O-rings are available separately.
