Supertech Honda D16Z6 Black Nitrided Exhaust Valve - +0.5mm Oversize - Single

Supertech is known for making well-built internal engine components, and this black nitrided exhaust valve for the Honda D16Z6 is no exception. If you're rebuilding the top end of your D16Z6 engine, these valves are a solid option for replacing worn-out stock units.

This particular valve is 0.5mm larger than the factory size, which can help restore lost compression or even slightly increase it if your valve seats are in good condition. The black nitriding process hardens the surface of the valve, making it more resistant to wear and heat, which is important for exhaust valves that see high temperatures. It's a single valve, so you'll need to order the correct quantity for your engine.
