The Kibblewhite KPMI Intake Valve Guide is precision-machined from high-quality cast iron, designed for durability and performance. Engineered to be compatible with unleaded fuel and suitable for any valve-stem material, this guide ensures reliability in high-temperature conditions. Kibblewhite employs a proprietary cast iron composition, formulated with specific elements such as carbon, silicon, manganese, nickel, chromium, copper, and sulfur. This results in a highly pearlitic structure with dense, fine grains, enhancing wear resistance and longevity. The guide features a minimal-impact profile to optimize airflow while maintaining critical cross-sectional thickness in high-heat zones, supporting both endurance and performance. With an overall length of 1.90" and an increased size of +.001", this intake valve guide is a high-quality upgrade for engine builders seeking precision and durability.
