20-2320 KPMI, intake valve guide. C630 bronze. STD

For high-performance Ironhead builds, heat management is everything. This KPMI intake valve guide is manufactured by Kibblewhite using C630 nickel-aluminum-bronze. This specific alloy is a favorite in racing and high-output applications because it transfers heat from the valve to the cylinder head much faster than traditional materials. This is a standard size guide with a 0.5650 inch outer diameter and a 1.77 inch overall length. It is engineered to fit 1957 to 1983 Harley-Davidson Sportster XL models. Whether you are refreshing a stock motor or building a track-ready Sporty, these bronze guides offer the toughness and thermal conductivity required for demanding conditions. This component is sold individually and represents the pinnacle of valvetrain technology for the classic Sportster platform.
