Billet oil filter mounting bracket for Twin Cam engines was specially designed and created for the S&S 124" Twin Cam engines, but makes a great cosmetic and functional upgrade for engines built with stock Twin Cam crankcases as wellNo voids or other casting defects in the material to cause leaksPosition of the filter has been shifted slightly to give additional clearance between the filter body and the crankcase for easier filter installation and removalAlso machined to make it easy to install an oil cooler in the pressure-side of the system; if a cooler is not needed, simply install the pipe plugs in the threaded holes in the filter bracket, instead of the hose fittingsMade in the U.S.A.
