The Kibblewhite RFS Engine Intake Valve is a precision-engineered component designed for optimal performance in KTM engines. Crafted from CNC-machined EV8 stainless steel forgings, this valve offers a lightweight yet robust construction that ensures durability and reliability under demanding conditions. Its one-piece forging profile is optimized for excellent flow characteristics, contributing to improved engine efficiency and power output. The valve undergoes a unique German infusion process to a depth of .002 inches, with a surface buildup of .0002 inches, significantly enhancing wear resistance, reducing friction, and providing superior corrosion resistance compared to traditional chrome or nickel plating. This advanced surface treatment ensures longer service life and consistent performance over time. Each valve is meticulously designed using Finite Element Analysis (FEA) software to optimize strength and durability while minimizing weight. Profiles are tested on a computerized flow bench to verify airflow efficiency, ensuring maximum performance in high-performance applications. The stems are coated with black nitroneg to further improve wear resistance and reduce friction during operation. Made in the USA, this intake valve combines precision engineering with durable materials to meet the demanding needs of KTM enthusiasts and professional mechanics alike.
