These polished billet oil filter brackets were originally created to complete S&S T124 engines, but they are an excellent upgrade for stock Harley-Davidson Twin Cam A engines as well The bracket places the filter slightly farther from the crankcase to allow just that little bit of extra clearance that makes installation and removal of the filter a little easier What makes this filter bracket really useful however, is that it is machined to allow oil to be routed to an oil cooler right from the filter mounting bracket
