This billet 6061 aluminum oil filter cap is manufactured right here in western Massachusetts, USA. We have made several improvements to the oil filter cap to ease the cartridge filter change.
A six point 2 1/2" socket design replaces the 64.5mm 14 flute factory design. This eliminates both the tool becoming stuck on the filter cap, and the resulting rounding of the corners. The socket for this nut is normally utilized for wheel bearings. It is very HD, I offer a nice quality affordable version here, or you may purchase your own.
Next, the factory spring valve is eliminated. An EZ Drain Valve is utilized for quick draining of the housing. The socket will fit over it.
Your stock filter mount tube/bypass valve is retained/reused. Cap fits all 6/8 cylinder applications.
