Supertech Performance GDE-T4AG-SM-8 Manganese Bronze Valve Guides for Toyota 4AGE 6mm Stem

These valve guides conduct heat from the exhaust valve into the cylinder head, providing critical thermal management for high-performance applications.

Key Features:

• Precision-machined from high-quality manganese bronze material
• Designed for both intake and exhaust applications on Toyota 4AGE 16v engines
• Compatible with 6mm valve stems and must be used with VS-T6SM valve stem seals
• Provides optimal performance and durability when combined with low friction nitrated valves
• Set includes 8 valve guides for complete engine rebuild or replacement

For high-powered engines requiring better thermal transfer, manganese bronze offers excellent heat dissipation properties, though copper alloy guides provide about 3 times higher thermal transfer than manganese bronze. Supertech provides the racing market with superior valves and valve train components for virtually every type of racing, including drag racing, rally, and road racing.

This valve guide set is engineered to deliver maximum durability and performance in demanding motorsport environments, making it an essential component for serious Toyota 4AGE engine builds.
