Supertech Toyota MR2 3SGTE Black Nitride Exhaust Valve - +0.5mm Oversize - Set of 8

The black nitride coating on these Supertech exhaust valves is a notable detail, offering improved surface hardness and reduced friction. This is important for the exhaust valve's job of sealing the combustion chamber and handling the intense heat and pressure of combustion in your Toyota MR2's 3SGTE engine. These are a +0.5mm oversize set, meaning they are slightly larger than stock to help refresh worn valve seats or improve sealing in a performance build.

Supertech is known for making well-built valvetrain components, and this set of eight valves is no exception. The black nitride treatment not only helps them resist wear but also contributes to better oil retention, which can be beneficial for lubrication under high-stress conditions. Because they are a specific oversize, they are intended for engines where the valve seats have been machined to accept them, often as part of a rebuild or performance upgrade.

If you're rebuilding the top end of your 3SGTE engine, especially if you're looking to refresh worn components or tune for better performance, this set of eight +0.5mm oversize exhaust valves from Supertech is a solid option. They are designed to fit the specific needs of the MR2's engine, providing a durable and effective replacement for your original valves.
