Billet aluminum oil filter housing cap that replaces the factory cap and adds provision for an external oil cooler, with two 1/8" NPT ports and two AN10 fittings for cooler lines and/or temp/pressure sensors - useful on a car that's tracked or tuned and running hotter oil temps than stock. CNC-machined and anodized rather than the OEM plastic cap, which is prone to cracking.

Fitment: BMW M52/M54/M56 six-cylinder engines - E36/E46 3 Series, E39/E60/E61 5 Series, E53 X5, E83 X3, Z3 and Z4 (E85).
