Stef’s, the acclaimed oil pan maker from New Jersey, is celebrating its 20-year anniversary with the introduction of a unique, new oil filter adapter for LS engines. It is the first of its kind. For the able LS engine trans-planter, the problem has not been one of finding the desirable power unit, rather one of getting it to fit within the surroundings of a different engine bay. Often the original cast aluminum oil pan presents clearance issues. Horizontally mounted, Stef’s new oil filter adapter will fit all LS engines with aftermarket steel oil pans, including the LS1, 3, 4, 5, 7, and 9. It also fits aftermarket blocks including those of Dart, Chevy LSX, RHS, and World. Designed for convenience with easy filter changing and improved header clearance, Stef’s new adapter features internal oil passageways of 5/8in diameter, offers provision for oil cooler hoses, and is supplied complete with oil filter and mounting hardware. The adapter kit comprises the adapter body, which is made of billet aluminum 6061 T6; filter element; mounting bolts and O-rings that seal the adapter to the oil pan; two removable AN-8 bungs, for oil cooler hoses; and a nipple to secure the oil filter to the adapter. Assigned with part number 6742, Stef’s complete LS oil filter adapter kit is priced at $240.30 and is available for immediate delivery.
