What is the benefit of the Black Nitride finish?

The Black Nitride finish hardens the valve surface, which helps reduce friction and improve wear resistance. This means the valves are designed to last longer and operate more smoothly in the engine.

Are these valves a direct replacement for stock?

Yes, these valves have a 30mm diameter, which is the stock size for the Honda/Acura K20A2, K20A, and K24A2 engines, making them a direct fit for a cylinder head rebuild.

What other parts are typically needed for an exhaust valve replacement?

When replacing exhaust valves, you'll also need valve seals, and often valve springs and retainers, depending on the condition of your existing components and your engine's intended use.

Product Details

If you're rebuilding the top end of your Honda or Acura K20A2, K20A, or K24A2 engine, these Brian Crower exhaust valves are a solid choice. They are designed to handle the heat and stress that comes with performance engine work, ensuring reliable operation after your rebuild.

These valves feature a Black Nitride finish, which is a surface treatment that hardens the valve face and stem. This treatment helps reduce friction and improve wear resistance, meaning the valves will last longer and operate more smoothly within the valve guides. The 30mm diameter is a direct replacement for the stock size on these popular K-series engines, making installation straightforward when you're putting your cylinder head back together.
