Description The AIRTEC Billet Oil Filter Housing Cap for your BMW N54/N55/S55 engines is a much more robust solution as the plastic OEM housing is known to become brittle and fail over time. The AIRTEC Motorsport billet oil filter housing is machined from billet aluminium, is anodised in grey and features the AIRTEC logo engraved on top. This is an easy fit and makes use of the original O-Ring, Filter cage & filter design.
