This oil filter socket is a perfect fit for the Motorcraft oil filter FL-500S older style with 30 flutes only. There are two versions of the FL-500S from Ford Motorcraft now. The newer ones only 14 flutes and this socket does not fit them. This will not fit the FL-500S we have in stock. The socket is from Lisle Tools and is 3.8 drive. The socket is low profile, less the 1 inch tall once it is placed on the filter. Do not use 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. Shipping charges and options are based on your zip code and will show the amount in checkout.
