The BMW N55 responds well to upgrades and replacing the factory air filter for an ITG foam filter is a cheap and easy way to unlock some additional power. Having been tested and seen an increase of power and torque it's a worthwhile breathing modification for the 3.0ltr N55 engine found in the M135i, M235i and M2
Designed as a direct replacement item that can be changed in a matter of minutes, this upgrade air filter is something that can be serviced with the ITG cleaner kit, rather then being thrown away like the factory air filter come service time.

Why foam? Because, compared to paper or other filter technologies, reticulated polyester foam achieves optimum performance against three key criteria:
the ability to allow air to pass through without causing a large drop in pressure.
the capability to arrest a high proportion of airborne dust while feeding the engine clean air.
the capability to absorb a large amount of dust without reducing air flow capacity.
