1997-2013 Engine Billet Oil Bypass Delete Gen III or IV LS Engines

Keep unfiltered oil out of your engine by plugging off the oil bypass check valve. The factory bypass check valve can let unfiltered oil into your engine's bearings and lifters.


This Billet Bypass Delete Plug replaces the factory check valve, preventing unfiltered oil from getting into the engine.  The factory bypass check valve is a safety in case the oil filter never gets changed and the filter gets restricted. Most oil filters already have a bypass built into them for this reason.  


Install one of our Billet Bypass Delete Plugs the next time you change your oil filter. 


A 1/4-20 threaded hole in the end of our Bypass delete is for easy removal. Just screw a 1/4-20 bolt in and pull the delete out if ever necessary.  Better engine protection from less particles bypassing, replaceable High Temperature Viton O ring and for ease of service a threaded 1/4-20 hole. Why would you ever let unfiltered oil into your expensive LS engine?


To keep even more unfiltered oil from going through the system check out our Precision Billet Barbell Oil Diverter. Not only does it keep unfiltered oil out, it improves oil flow.


Tech Note: Always make sure your oil is at operating temperature before running your engine hard! Also use a high quality oil filter!


Note: Make sure your Bypass valve is located in the filter adapter housing like in the photo BEFORE ORDERING! Some bypass valves are located in the oil pan.
