**Kibblewhite KPMI Intake Valve Guide +.003 - Cast Iron** This precision-machined cast iron valve guide is engineered for durability and high performance. Designed to be compatible with unleaded fuel, it accommodates any type of valve stem material. Kibblewhite has developed a proprietary cast iron blend, incorporating elements such as carbon, silicon, manganese, nickel, chromium, copper, and sulfur. This composition results in a highly pearlitic structure with dense, fine grains, ensuring excellent wear resistance. All KPMI guide profiles are designed to minimize airflow disruption while maintaining critical cross-sectional thickness in high-temperature areas, promoting endurance and performance. Strict manufacturing tolerances are maintained for ID/OD dimensions and cylindricity, ensuring precision fitment and longevity. This guide is designed with a +.003" oversize specification for applications requiring an increased fit tolerance.
