ZRP Intake Vave Guides for Mitsubishi Evo 4G63 8 pcs.

Mitsubishi 4G63 EVO 1–9 – ZRP High Performance Intake Valve Guides (Set of 8 pcs)

ZRP High Performance Intake Valve Guides are engineered specifically for Mitsubishi 4G63 engines used in Lancer Evolution I–IX models. Designed to withstand extreme boost pressure, elevated cylinder temperatures, and sustained high-RPM operation, these valve guides provide exceptional durability, dimensional stability, and efficient heat dissipation in demanding street and motorsport applications.

Manufactured from premium copper-based alloys such as Manganese Bronze or Copper Beryllium, these intake valve guides offer outstanding wear resistance and superior thermal conductivity. The advanced material composition ensures rapid heat transfer from the valve stem to the cylinder head, effectively reducing operating temperatures and enhancing overall valvetrain reliability under high load.

Each guide is precision-machined to strict tolerances (±0.01 mm), guaranteeing accurate valve alignment and consistent sealing performance. The optimized internal surface finish minimizes friction, improves lubrication film stability, and reduces wear during prolonged high-speed and high-temperature operation.

Designed as a direct-fit replacement for OEM components, ZRP intake valve guides are suitable for performance street builds, high-boost turbocharged setups, and professional motorsport engines where durability and consistency are critical.
