Kibblewhite Exhaust Valve Guide Bronze Std Fits Honda

• Type: Valve Guide

The Kibblewhite Precision Machining (KPMI) Exhaust Valve Guide for Honda engines is engineered for optimal airflow and durability. Made from C630 Racing Bronze, it contains 80% copper for excellent heat conductivity, 5% nickel for superior wear resistance, and 10% aluminum for compatibility with aluminum cylinder heads. The guide's profile is designed to minimize airflow disruption while maintaining necessary thickness in high-temperature areas, enhancing both performance and longevity. A precision-machined flange ensures proper installation without repeated measurements, while a radius transition prevents galling. Tight concentricity tolerances help maintain ideal valve seat alignment, reducing material removal during valve jobs and maintaining consistent combustion chamber volumes. The high-quality material composition also allows for tighter clearances, improving valve-to-seat sealing and oil control. Sold in sets of two unless otherwise noted, this premium valve guide is designed for off-road performance applications.
