Now available, The new Slim JIMS® Oil Filter Wrench, No. 941. It is the slimmest oil filter wrench on the market. Why? Because this exclusive design makes it much easier to navigate near both the oil cooler and the crankcase position sensor, and allows you more room to work around the exhaust pipes, frame, hoses and brackets, etc.
This tool incorporates a 3/8” square drive and guarantees a good grip on any H-D spin-on oil filter with a 14-flute end. JIMS® Slim Jim Oil Filter Wrench is manufactured in the U.S.A. with an MSRP of $32.17, and like hundreds of other JIMS tools is backed by their lifetime warranty. Call 805-482-6913 or visit JIMS USA
That looks like it would work great. I would also like to see one made to fit the S&S oil filters that I use.
