Supertech VW/Audi 7mm Viton Exhaust Valve Stem Seal - Set of 12

Supertech is known for making solid internal engine components, and these 7mm Viton exhaust valve stem seals are a great example of that. If you're rebuilding the top end of your VW or Audi engine, replacing these seals is a crucial step to prevent oil from getting into your combustion chambers. These seals are made from Viton, a material that holds up well to the heat and chemicals found in exhaust ports.

Using Viton for exhaust seals is a smart choice because it can handle the higher temperatures that exhaust valves experience compared to intake valves. This helps ensure they don't break down prematurely, which could lead to increased oil consumption and fouled spark plugs. This set includes 12 seals, which is what you'll need for a typical 4-cylinder engine, making it a convenient package for your rebuild.
