The Kibblewhite KPMI Intake Valve Guide is precision-machined from cast iron and designed for high performance and durability. Engineered to minimize impact on airflow while maintaining critical cross-sectional thickness in high-temperature areas, it ensures excellent endurance. Compatible with unleaded fuel, it accommodates any valve stem material. Kibblewhite uses a proprietary cast iron formulation, specifying elements such as carbon, silicon, manganese, nickel, chromium, copper, and sulfur. This results in a highly pearlitic structure with dense, fine grains for superior wear resistance. Strict attention is given to ID/OD tolerances and cylindricity to ensure reliable performance.
