Supertech VW 1.8L/2.0L 8V Black Nitrided Exhaust Valve - +2mm Oversize - Set of 4

If you're rebuilding the top end of your VW 1.8L or 2.0L 8-valve engine, especially if you're looking to improve airflow or replace worn components, these Supertech exhaust valves are a solid option. They are designed to be a direct replacement for your stock valves, but with some key upgrades that can make a difference in performance and durability.

These valves are 2mm larger than stock, which helps increase the flow of exhaust gases out of the combustion chamber. This can lead to a slight improvement in engine breathing and potentially a bit more power. The black nitriding treatment on the surface hardens the valve and makes it more resistant to wear and corrosion, which is important for longevity, especially in performance applications. This set includes four valves, enough for one engine.
