Oil System Improvement Parts-LS Billet Oil Bypass Delete

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 when there are quick oil pressure fluctuations. Our Billet Bypass delete plug replaces the factory check valve helping to prevent unfiltered oil from entering critical engine parts.  The factory bypass check valve is a safety in case the oil filter gets restricted. Most oil filters already have a bypass built into them for this reason.  Install one of our Bypass Deletes the next time you change your oil filter for better engine protection from less particles bypassing. It has a replaceable High Temperature Viton O ring and for ease of service a threaded 1/4-20 hole for easy removal. Just screw a 1/4-20 bolt in and pull the delete out if ever necessary. 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, but it also 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!
