An oil filter by-pass adapter for placement between an internal combustion engine block and a spin-on type oil filter comprising a wafer plate having a first face adapted to contact the engine block, and a second face adapted to contact the oil filter. The second face has a peripheral wall to retain the oil filter. A central through passage extends through the wafer and provides clearance for the oil to enter and exit the oil filter. There is a choked flow oil conduit from the input oil stream having at least one oil transfer passage which takes oil from before the oil filter and passes it to an oil transfer channel. The oil filter by-pass adapter can be an ultra high molecular density plastic or aluminum. The oil filter by-pass adapter oil transfer passages are between 1/64- 7/64 inches in diameter and the oil transfer channel is between 3/64-¼ inches in diameter.
