What is an Oil Filter Sandwich Adapter?

An Oil Filter Sandwich adapter is an adapter that mounts between your engine block and oil filter, featuring four 1/8 NPT ports that allow you install your oil sensors and feed lines without the need to drill into your oil pan or remove your stock sensors. There are multiple sensor openings on each oil filter sandwich plate allowing for a variety of mounting option.

Most of our Oil Filter Sandwich adapters are only compatible if the gasket diameter of your oil filter is 3 inches or less. We recently released a new oil filter adapter for the Chevy Small Block 305/350, which has a 13/16-16 thread and is only compatible if the gasket is 4 inch in diameter.
