Supertech Toyota Yaris / Echo 4AGE 20V 5mm Viton Exhaust / Intake Valve Stem Seal - Single

Made from Viton, these valve stem seals are built to handle the heat and chemicals found in your engine's exhaust and intake ports. They're designed to fit the 4AGE 20V engine found in Toyota Yaris and Echo models, specifically for the 5mm valve stems.

Properly sealing the valve guides is crucial for preventing oil from entering the combustion chamber. This helps maintain engine performance, reduce oil consumption, and keep emissions in check. These seals are a direct replacement for the original parts, ensuring a straightforward installation when you're rebuilding or refreshing your engine's top end.
