Supertech Scion tC 2AZFE / Toyota Celica 1ZZ/2ZZ 5.5mm Viton Exhaust Valve Stem Seal - Set of 12

These Supertech valve stem seals are made from Viton, a material known for its excellent resistance to heat and oil, making them a solid choice for exhaust valve applications where temperatures can get quite high. Each seal features a 5.5mm inner diameter, specifically designed to fit the valve stems on Scion tC 2AZFE and Toyota Celica 1ZZ/2ZZ engines.

When you're rebuilding an engine or just replacing worn valve seals, using the right material is key to preventing oil from getting into the combustion chamber. Viton holds up much better under the heat of the exhaust side than standard rubber seals. This set includes 12 seals, enough for a typical 4-cylinder engine with both intake and exhaust valves needing attention, though these are specifically intended for the exhaust side.
