Active Autowerke BMW E9x M3 Air Filter Specs And Benefits
- Green High Performance Air Filters are uniquely designed to take full advantage of cottons capabilities.
- Unlike multi-layer gauze filters which can fray and release fiber particles into your engine, The Active Autowerke BMW M3 Filter uses two layers of tightly-interwoven cotton fabric. The 3 main benefits to woven cotton are the fact its thinner, holds oil better, and is stronger. Since its thinner, it allows better air flow without sacrificing filtration. The cotton holds the oil more evenly, and the medium is much stronger. Unlike gauze, you cannot wear a hole in woven cotton by rubbing it, and there is no way small bits of cotton can rip off since its interlocked with another piece.
- Direct OEM like fit with superior quality
- These filters are coated in steel mesh for extra strength and durability, because of this, Green filters are much more dent resistant.
- These USA filters offer fully seam welded, powder coated, laser cut steel housing with pre-assembled rubber seals on our intake housings.

Active Autowerke BMW F-Chassis N55 X-Drive Charge Pipe
2012 – BMW F3X X3, X4, 335ix, 435ix X-Drive with N55 engine
Active Autowerke is familiar with some of the issues that 2012 and newer N55 BMW X-Drive X3, X4, 335ix, 435ix owners experience even running with the factory BMW boost.
The BMW N55 utilizes an all plastic construction for the factory charge pipe.
This charge pipe will eventually break, it is just a matter of time and when. Whenever the factory charge pipe break at the plastic seam, the engine immediately senses a huge vacuum leak where the engine ECU counters by sending the engine into LIMP MODE condition. Usually, the car’s performance will feel dimished and lack luster as if running without a proper firing cylinder.
The Active Autowerke N55 Charge Pipe is a designated product designed from inception to cure and eliminate this problem on your BMW. This new version is designed for X-Drive cars.
Constructed from all aluminum makes this charge pipe almost indestructible.u00a0
The connection to the throttle body is a CNC machined part to duplicate the factory fit as well making a tight, reliable seal.
Owners of BMW with the N55 engine understands that additional power can be reliably maintained with the use of Water/Methanol injection as an added feature. However, the N55 current does not have a reliable source to accommodate the application of Water/Methanol nozzles.
The Active Autowerke N55 Charge Pipe has a proper provision for this specific application. A boss with two separate ports are provided upstream where the injected mix of water/methanol can properly atomize before entering the engine.u00a0The thread depths for the water/methanol nozzles are also checked to allow for a proper spray pattern without hitting the inside walls of the threaded holes.
The BMW N55 engine does not utilize external diverter valves like it’s N54 predecessor. Rather, the BMW N55 has diverter valves that are built inside the engine turbo compressor housings and no in the charge pipe.As such, there are no provisions to add larger BOVs.
Key Features:
- Specific design to correct a problem with X-Drive cars
- Consistent diameter tubing for increased performance
- Increased throttle response and decrease throttle lag
- CNC machined throttle housing for a proper seal
- Retains factory BMW O-Ring seal
- Provision of raised boss for 2 Water/Methanol nozzles
