OVERVIEW
The Active Autowerke N55 charge pipe in the version designed specifically for X-Drive cars: 2012 and newer BMW F3X X3, X4, 335ix and 435ix models 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
