Ferrea Ford Zetec ZX2 5.5mm Viton Hi-Temp Exhaust Valve Stem Seal - Single (Drop Ship Only)

If you're rebuilding the top end of your Ford Zetec engine, especially for a ZX2, getting the valve stem seals right is crucial. These Ferrea seals are made from Viton, a material known for its ability to handle high temperatures, which is exactly what you need for exhaust valves. Properly sealing the valve stems prevents oil from getting into the combustion chamber, which helps reduce smoke and oil consumption.

Ferrea uses Viton for these seals because it holds up well under the heat generated by exhaust gases. The 5.5mm size is specific to certain Ford Zetec applications, ensuring a snug fit on the valve stem. Installing these seals is a standard part of many engine rebuilds, helping to restore proper engine function and emissions.
