The Kibblewhite KPMI Exhaust Valve Guide is precision-machined from high-quality cast iron to ensure durability and performance. Designed to be compatible with unleaded fuel, it accommodates any type of valve stem material. Kibblewhite develops its own exclusive cast iron specification, incorporating elements such as carbon, silicon, manganese, nickel, chromium, copper, and sulfur. This composition results in a highly pearlitic structure with dense fine grains, providing excellent wear resistance. All KPMI valve guide profiles are engineered to minimize airflow disruption while maintaining critical cross-sectional thickness in high-temperature areas, promoting both high performance and endurance. Strict attention is given to inner and outer diameter specifications, as well as cylindricity, to ensure precise fitment and reliability. This model features a +.001" oversize for applications requiring a slightly larger guide.
