Ford 6.0L/6.4L Power Stroke™ Diesels
To ease installation of the BMK21 on 2003 and later model Ford pickups equipped with the 6.0L and 6.4L Power Stroke™ diesel engines, AMSOIL offers the new Aluminum Billet Oil Filter Cap (BK1101), the Aluminum Billet Oil Fill Cap (BK1102) and the 90-degree JIC Elbow (BP242, two recommended) (all sold separately). These new high-quality billet aluminum caps replace the original equipment manufacturer (OEM) filter cap and oil fill cap. The new caps have holes tapped in them that accept the JIC elbows for hose connectors.
