Designed for classic Chevrolet V8 applications, this oil filter adapter with bypass is a reliable OEM style solution for engines that need secure, efficient oil filtration. It is engineered to bolt on to Small Block Chevy models from 1968 to 1999, excluding LT1 engines, and Big Block Chevy Mark IV engines from 1968 to 1989. With a 13/16"-16 thread size, it provides the correct fitment for compatible filter setups and helps maintain proper oil system performance.

This adapter mounts the oil filter in the factory style position and incorporates a bypass function that allows oil to continue flowing if the filter becomes restricted. That means your engine can still receive adequate oil delivery in demanding conditions, helping support consistent lubrication during street driving and most race applications. Built for direct fit convenience, it is a practical choice for restorations, maintenance, or performance upgrades where dependable oil flow is essential.
