Engineered as one-piece forgings, KPMI Black Diamond intake valves combine lightweight construction with the structural strength required for high-performance applications. The valve profiles are specifically designed to deliver excellent flow characteristics, ensuring optimal air management within the combustion chamber.
These stainless steel components feature a specialized German impregnation process that penetrates to a depth of .002” with a surface buildup of .0002”. This Black Diamond™ treatment significantly enhances wear properties and reduces friction, offering superior resistance to corrosion and wear compared to traditional chrome and nickel electrolysis plating.
