Active Autowerke xDrive Charge Pipe – BMW 335i xDrive / 435i xDrive / X3 / X4 (F Chassis)

OVERVIEW

The Active Autowerke N55 charge pipe in the version designed specifically for X-Drive cars: 2012 and newer BMW F3x 335i xDrive and 435i xDrive, plus the F25 X3 and F26 X4, with the N55 engine. The BMW N55 uses an all-plastic factory charge pipe that will eventually break at the plastic seam — it is a matter of when, not if — and when it does the ECU senses a large vacuum leak and sends the car into limp mode. This all-aluminum replacement was designed from inception to cure that problem, is almost indestructible, and adds a raised boss with two upstream ports for the water/methanol nozzles the N55 otherwise lacks a factory provision for, so the mix atomizes properly before entering the engine.

SPECS

• Designed specifically to correct the problem on X-Drive cars
• 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 X-Drive charge pipe
• High quality silicone couplers
• Stainless steel clamps
• Not included: the factory throttle clip and O-ring
