Supertech Honda D16A1 Black Nitrided Exhaust Valve - +0.5mm Oversize - Set of 8

If you're rebuilding the top end of your Honda D16A1 engine, these Supertech exhaust valves are a solid option. This set includes eight valves, each measuring 0.5mm oversize. This helps to ensure a good seal in the valve seat, especially if the original seats have seen some wear or have been reconditioned.

These valves are treated with a black nitriding process. This surface hardening technique makes the valve stem more durable and resistant to wear, which is important for consistent performance over time. The oversize nature of these valves means they are intended for engines that may have had their valve seats machined to accommodate them, or for those looking to achieve a precise fit during a performance build.
