This oil filter socket is available in two versions. There are two versions of the FL-500S from Ford Motorcraft now. Motorcraft oil filter FL-500S older style with 30 flutes or the newer ones has only 14 flutes. The new style will fit the FL-500S we have in stock. The socket is from Lisle Tools and is a 3.8 drive. The socket is low profile, and less than 1 inch tall once placed on the filter. Do not use it with an impact. It fits tightly so as not to slip once on the filter. This listing is sold individually and does not include the oil filter.
