Product Description

The GSC Power-Division 3142-12 intake valve guide set is engineered for Toyota vehicles equipped with the legendary 2JZ-GTE turbocharged inline-6 engine. Made from manganese bronze - a material known for its excellent wear resistance and thermal conductivity - these intake valve guides help maintain consistent valve positioning in high-stress and high-RPM conditions. This stopper-style guide design improves valvetrain stability and helps reduce wear on critical components, making it a solid upgrade for engines subjected to performance tuning or racing conditions.

This complete set of 12 intake guides is a direct replacement for the original Toyota guides on Supra Turbo and select Aristo/Lexus GS300 2JZ-GTE engines, ensuring precise fit and reliable operation. Whether you're rebuilding your engine or upgrading for higher performance, these manganese bronze guides provide enhanced durability, better heat handling, and improved valve control compared with stock guides.
