GSC Power-Division 4G63 Manganese Bronze Stopper Style Exhaust Valve Guides (Set of 8) - MPN 3003-8
This product will be available for sale in 2 weeks, but you can pre-order now to receive 10% discount!
Fits 1990-2006 Mitsubishi Eclipse, Lancer Evolution, Galant VR-4, Eagle Talon, and Plymouth Laser with 4G63 engines.
GSC Power-Division manganese bronze exhaust valve guides are engineered for high-performance cylinder heads where heat dissipation and lubricity are paramount. These guides utilize a stopper style design, which provides a positive stop during installation to ensure consistent seat height and prevents the guide from migrating in the cylinder head under extreme thermal stress.
- CNC machined from high-strength manganese bronze for superior wear resistance
- Stopper style design ensures precise installation depth and prevents guide movement
- Superior heat transfer characteristics compared to OE cast iron guides
- Specifically designed for the exhaust side to withstand higher operating temperatures
- Manufacturer Part Number: 3003-8
- Quantity: Set of 8
