FAQ
Do I need one kit or two to service my 7.3L PowerStroke?
One kit services one cylinder head (8 valves). The 7.3L engine has two heads, so you’ll need two kits to replace seals on all 16 valves.
Are these seals suitable for both intake and exhaust valve stems?
Yes—the fluoro-elastomer positive-type top-hat seals in this kit are engineered to work for both intake and exhaust valves in the 7.3L PowerStroke when installed per OE spec.
Is this an OEM-quality replacement?
Yes—These seals meet or exceed OE specifications, manufactured by Mahle with factory-grade materials and precision.
