    A must-have kit to maintain high oil pressure in 7.3L Power Stroke engines. Made with high-quality, temperature- and oil-resistant materials. Prevents leaks and pressure loss that can affect engine performance.

    Great kit, also comes with the o-ring for the plug on back of H-POP which often leaks, also you must use loctite 680 on the first 3 threads of that plug when reinstalling it. It was one of the main sources of my engine valley leak. I discovered it with a mechanics mirror, the bottom of the plug was wet with oil. back to a dry engine valley. Thanks Clay

    just dont be like me open too many kits at once and then get confused to what goes where as I had other o-ring kits for other things. My only beef,is if you live in Canada and you place an order, be patient the USPS charges one thing for delivery, then Canada Post charges an extra fee for duties and taxes.
