Supertech Toyota 86 5.5mm Stem Viton Intake & Exhaust Valve Stem Seal - Set of 16

Supertech is known for making well-built engine components, and these valve stem seals for your Toyota 86 are no exception. If you're rebuilding your engine or just replacing worn-out seals, these are a solid option. They are designed to fit 5.5mm valve stems and are made from Viton, a material that holds up well to heat and oil.

This set includes 16 seals, which is enough for a typical 4-cylinder engine like the one in the 86. Viton seals are a popular choice because they offer improved resistance to degradation from engine oil and high temperatures compared to standard rubber seals. This helps prevent oil from leaking past the valve guides and into the combustion chamber, which can cause blue smoke on startup and increased oil consumption.
