If you're rebuilding the top end of your Toyota Supra's B58 3.0L engine, especially if you're pushing more power or looking for improved reliability, a fresh set of exhaust valves is a critical component. These Ferrea valves are built to handle the heat and stress of performance applications, ensuring your engine breathes efficiently under demanding conditions. They are designed as a direct replacement for your stock exhaust valves, making the installation process straightforward for a qualified mechanic.

Ferrea has a solid reputation for making well-built engine components, and these valves are no exception. They feature a specific material composition and heat treatment process that helps them resist wear and deformation, even at higher operating temperatures. The 21-degree tulip face angle is a common design that helps promote good sealing against the valve seat, which is essential for maintaining compression and preventing backflow. Each valve measures 28.5mm in diameter with a 5.96mm stem and a overall length of 99.8mm, ensuring they fit precisely within the cylinder head and work with your existing valvetrain components.

This set includes 12 exhaust valves, enough to cover all cylinders in your B58 engine. When undertaking a rebuild of this caliber, using high-quality replacement parts like these Ferrea valves can make a significant difference in the longevity and performance of your engine. It's always recommended to consult your vehicle's service manual or a professional mechanic for specific installation procedures and any other components you might need to replace during your engine build, such as valve springs or seals.
