Active Autowerke Charge Pipe Upgrade Kit – BMW N55 (F22 / F30 / F32 / F87)

OVERVIEW

The Active Autowerke F-Chassis N55 charge pipe fits 2012 and newer rear-wheel-drive BMW F2x / F3x / F87 335i, 435i, M235i and M2 models with the N55 engine, whose all-plastic factory charge pipe will eventually break at the plastic seam — a matter of when, not if. Once it does, the engine immediately senses a large vacuum leak and the ECU sends the car into limp mode, leaving performance diminished and lackluster. Designed from inception to cure that, its all-aluminum construction is almost indestructible and its CNC machined throttle body connection duplicates the factory fit for a tight, reliable seal. A boss adds two ports upstream so injected water/methanol atomizes properly, with thread depths checked so the nozzles spray without hitting the walls of the threaded holes.

SPECS

• All-aluminum construction
• CNC machined throttle body housing for a proper seal, duplicating the factory fit
• Retains the factory BMW O-ring seal
• Consistent diameter tubing for increased performance
• Raised boss with two ports for water/methanol nozzles, positioned upstream for proper atomization
• Black powder coated finish for an OEM look
• Increased throttle response and reduced throttle lag
• No provision for an external blow-off valve — the N55 diverter valves are internal to the turbo compressor housing

PARTS INCLUDED

• Active Autowerke N55 charge pipe
• High quality silicone couplers
• Stainless steel clamps
• Not included: the factory throttle clip and O-ring
