Supertech Renault Clio F7R 710 Williams 2.0L Black Nitrided Exh Valve - +1mm OS - Single (D/S Only)

If you're rebuilding the top end of your Renault Clio with the F7R 710 Williams 2.0L engine, you'll want to make sure your exhaust valves can handle the heat and stress. This Supertech exhaust valve is designed to be a direct replacement, but with some key improvements to help it last longer and perform better.

This particular valve is made from strong steel and has a black nitrided surface treatment. That nitriding process hardens the surface, making it more resistant to wear and corrosion, which is crucial for exhaust valves that see a lot of heat. It's also a +1mm Oversize valve, meaning it's slightly larger than the stock valve. This can help improve flow into the cylinder, especially if you've done other work to the engine. It's sold individually, so you can replace just the ones you need.
