Intake/Exhaust Valve Guide

KPMI Intake/Exhaust Valve Guide

Premium material and precision design engineered for high-performance engines. KPMI valve guides are manufactured from C630 nickel bronze to deliver exceptional wear resistance and thermal conductivity where it matters most.

• Material: C630 nickel bronze (≈5% nickel, ≈80% copper)
• Wear resistance: Nickel content provides superior durability under heavy valve seating and reciprocation
• Heat dissipation: High copper content ensures rapid heat transfer away from the valve stem and guide bore
• Aerodynamic profile: Optimized guide geometry minimizes airflow disruption while maintaining necessary cross-sectional strength in high-temperature zones
• Performance & longevity: Designed to promote consistent valve seating, reduced thermal stress and extended component life

Ideal for racing, performance and heavy-duty applications where reliable valve control and thermal management are critical. Trust KPMI to combine metallurgy and engineering for improved endurance and engine efficiency.
