The Alfa Romeo 4C BMC air filter is a superb drop-in panel style air filter that increases airflow while retaining OEM fitment.

A direct drop in for the 4C coupe and spider models. BMC uses proprietary materials that allow an increased air flow combined with more efficient filtration, guaranteeing containment of all impurities from as small as 7 microns (compared to OEM's 10 microns).

BMC filters are made of a multi-layered cotton gauze soaked with low viscosity oil covered with an epoxy coated alloy mesh to ensure protection from petrol fumes and oxidization due to air humidity. This is a proven design to get the most airflow in your Alfa while retaining the factory airbox.

BMC air filters come pre-oiled, and they can be washed and regenerated by using the appropriate BMC regeneration kit. (not included) Made in Italy.
