Kibblewhite Precision Guide Intake +0.001in

• Type: Valve Guide

The Kibblewhite Precision Intake Valve Guide (+0.001") is engineered for optimal airflow and durability. Its design minimizes obstruction to the airstream while maintaining critical thickness in high-temperature areas, enhancing both performance and longevity. Constructed from premium C630 Racing Bronze or cost-effective Manganese Bronze, these guides offer excellent wear resistance and thermal conductivity. The C630 Bronze, with 80% copper and 5% nickel, provides superior durability and heat dissipation. Manganese Bronze guides are easier to ream and finish, making them ideal for budget-conscious builders. Precision manufacturing ensures tight concentricity tolerances, reducing material removal during valve jobs and maintaining consistent chamber volumes. A built-in flange or diameter reduction (depending on fitment) simplifies installation by setting the correct guide protrusion automatically. Designed for high-performance applications, these valve guides resist galling, allow for tighter clearances, and improve valve-to-seat sealing and oil control. This kit includes two intake valve guides.
