GSC Power Division 4B11T Exhaust Valve Guide Set

Maximize the reliability of your Mitsubishi 4B11T engine with the GSC Power Division Manganese Bronze Exhaust Valve Guide Set. Specifically designed for the Lancer Evolution and Ralliart platforms, these guides are constructed from premium manganese bronze to handle the high exhaust gas temperatures associated with turbocharged performance engines.

Technical Advantages

• High-Temperature Resilience: Manganese bronze maintains its structural integrity under extreme heat, preventing guide deformation.
• Enhanced Lubrication: The material properties help maintain a consistent oil film, reducing friction between the valve stem and guide.
• Performance Fit: Engineered for the 4B11T cylinder head to ensure precise valve alignment and seating.
• Complete Set: Includes 8 guides, providing everything needed for a full exhaust-side cylinder head rebuild.

The 4B11T engine is known for its tuning potential, but high-performance modifications place significant stress on the valvetrain. Replacing factory guides with GSC Manganese Bronze guides is a critical step in preventing valve-related failures. Whether you are building a daily-driven street car or a high-output track machine, these guides offer the durability and precision required to keep your engine running at its peak.
