Supertech Honda B16/B18C Black Nitrided Exhaust Valve - +0.5mm Oversize - Set of 8

If you're rebuilding the top end of your Honda B16 or B18C engine, these Supertech exhaust valves are a solid option. This set includes eight valves, each measuring 0.5mm oversize to help restore compression and performance in engines with worn valve seats or guides. The black nitriding treatment on these valves makes the surface harder, which can improve wear resistance and help them seal better.

Supertech is known for making well-built internal engine components, and these valves are no exception. The oversize design is crucial for engines that have seen a lot of miles and may require machining to bring them back to spec. The nitriding process not only adds durability but also creates a smoother surface that can reduce friction in the valve guide. This set is designed to fit specific Honda B-series engines, ensuring a direct replacement for your original parts after any necessary machine work.
