Supertech Honda K20/K24 Black Nitrided Exhaust Valve - Set of 8

These Supertech exhaust valves are black nitrided, a surface hardening process that makes the valve face tougher and more resistant to wear. This is a set of eight, designed specifically for Honda K20 and K24 engines, which are common in many popular Honda and Acura models. When you're rebuilding the top end of one of these engines, especially if you're looking for improved reliability or performance, quality valves are a critical component.

The black nitriding process not only increases surface hardness but also helps to reduce friction, which can contribute to better sealing and longer valve life. This treatment is particularly beneficial for exhaust valves, as they operate under higher temperatures and stress compared to intake valves. The material and hardening process work together to ensure these valves can handle the demands of regular driving and even more spirited use.

If you're working on a K-series engine build, whether it's a stock rebuild or a performance-oriented project, these valves are a solid option. They are designed to fit right into the stock valve seats, making installation straightforward for a mechanic familiar with these engines. Make sure you have a valve spring compressor tool handy for the installation process.
