The Derale Low Profile Pressure Relief Sandwich Adapter installs between the engine block and the oil filter to provide external oil lines for an engine oil cooler. The cast aluminum body is only 1 inch thick, so it lowers the factory oil filter just 1 inch from stock, and a built-in pressure relief valve protects the system. It has 3/8 inch NPT ports and is designed for engines with a 20 x 1.5mm filter thread.
