About this part

Product Details

Manley Performance is well-known for making strong engine components for racing applications. If you're rebuilding the top end of your 1986-1992 Toyota Supra 3.0L with the 7MGE-Turbo or 7MGTE engine, these Manley Race Series exhaust valves are a solid option.

These valves are built from stainless steel, which holds up well under the heat and stress of an engine. They feature chrome-plated stems and hard tips to reduce wear over time, and the under-head area is swirl-polished to help improve airflow into the cylinder. The combustion face is also fully machined for better efficiency. Manley offers these in a Race Master straight stem design, which is what you're looking at here, to fit your specific engine build.

These are a good choice for exhaust valves, especially if you're running alcohol-based fuels, as they're recommended for those types of engines. They are designed for engines operating under 8000 RPM, which covers most performance street and track applications.
