KPMI Black Diamond Intake Valve High-performance stainless steel intake valve engineered for durability, low friction and superior flow. Designed and manufactured by KPMI using the proprietary Black Diamond® impregnation process for long-lasting engine performance. Key Features Advanced Black Diamond® treatment: German impregnation to a depth of 0.002" with a surface build-up of 0.0002" for enhanced wear resistance. Reduced friction & corrosion: Surface chemistry lowers friction and resists corrosion and wear better than traditional chrome or nickel electroplating. One-piece forging: Lightweight, strong construction for consistent durability under high stress. Optimized flow profile: Precision-shaped head and stem deliver improved airflow and combustion efficiency. Benefits Longer valve life and reduced maintenance intervals Improved throttle response and engine efficiency Reliable performance in high-temperature, high-wear environments Choose the KPMI Black Diamond Intake Valve for proven aftermarket quality that outperforms conventional plated valves. Ideal for performance rebuilds and race applications where durability and flow matter.
