Kpmi Mang Intake Guide +.002

• Size: +.002"
• Type: Valve Guide

The Kibblewhite Manganese Bronze Valve Guide is designed for cost-conscious engine builders while maintaining precise KPMI tolerances. Made from C630 manganese bronze, it is softer than premium nickel aluminum bronze guides, making it easier to ream and hone using a simple electric or battery-operated drill-eliminating the need for expensive honing equipment. This guide is compatible with unleaded fuel and works with all types of valve stem materials, offering maximum durability with chromed valve stems. It features a tapered nose design to enhance flow characteristics while minimizing port obstruction. The guide has an overall length of 2.40", a top diameter of .560", and is machined for a standard .420" seal. It accepts OEM-style top hat valve seals (sold separately) and an OEM lower collar. Ideal for intake applications, this valve guide provides a balance between affordability and performance, making it a practical choice for engine builders.
