Fits select Honda D-Series engines including D15B, D16Y, D16Z6, and D17A. These Supertech Black Nitrided exhaust valves are engineered for high-performance builds where increased thermal loads and higher RPMs are expected.

By applying a specialized Black Nitride surface treatment, Supertech significantly increases the surface hardness of the valve and reduces friction within the valve guide. This process results in a smoother finish that resists carbon buildup and improves heat dissipation compared to standard chrome-plated valves. Precision-machined from high-tensile stainless steel, these valves ensure long-term reliability under extreme combustion chamber temperatures.
