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

If you're rebuilding the top end of your VW 1.8L or 2.0L 8-valve engine, new exhaust valves are a critical part of the job. These Supertech exhaust valves are designed to handle the heat and stress of combustion, helping to ensure your engine breathes freely and performs reliably. The black nitriding treatment on these valves adds a layer of surface hardness, which can improve wear resistance and extend their service life.

This set includes four exhaust valves, which is what you'll need for a typical 4-cylinder engine. The nitriding process not only makes the surface tougher but also helps to reduce friction, allowing the valve to seat and unseat smoothly. When installing these, make sure your valve guides are in good condition and properly sized for a smooth operation and a good seal.
