BMW B58 Billet CNC Remote Oil Cooler Adapter Plate. Convenient Oil Cooler Integration: Add a remote oil cooler to your BMW-powered vehicle (Gen 1 and Gen 2 B58 engine). The New Pumaspeed Racing Billet Oil Cooler Plate Upgrade has been developed to eliminate leakage between the solid aluminium adaptor plate and the -10 AN fittings that are screwed internally into the thicker plate.
