For those of you who push the engine hard and need to drop the oil temperature to a respectable level, this adapter bolts in place of your oil temp sensor housing on the C5 Corvette. Your sensor then threads into this adapter. Now you can run -10 lines to an oil cooler and keep you engine happy. Machined billet aluminum finished in "black", this is the same adapter that comes with our C5 oil cooler kits. Includes a gasket and two -10 fittings.
