Air Filters, For 2019-Up BMW X3 / X4 F97/F98

The panel / cylindrical air filter is commonly referred to as "replacement air filter". It is installed in the vehicle's original airbox to replace the Original Manufacturer air filter. It is made of highly performing materials that allow an increased air flow combined with a more efficient filtration, guaranteeing containment of all impurities from as small as 7 microns (compared to Original Manufacturer's 10 microns).
