Supertech VW/Audi 8mm Polyacrylic Intake Valve Stem Seal - Single

Made from polyacrylic, this 8mm intake valve stem seal from Supertech is built to handle the heat and oil exposure common in engine valve areas. When you're rebuilding an engine or just replacing worn-out seals, these are a solid option for keeping oil from getting past your intake valves and into the combustion chamber. A worn valve seal can lead to increased oil consumption and blue smoke from the exhaust, especially on startup.

This is a single seal, so you'll need to order one for each intake valve you're servicing. The 8mm stem size is a common fit for many VW and Audi engines, but it's always a good idea to double-check your specific application to ensure you're getting the right part. Proper installation is key to their function; they need to be seated correctly to prevent leaks.
