Supertech Toyota Supra 2JZ Black Nitrided Exhaust Valve - +1mm Oversize - Set of 12

This set includes 12 Supertech black nitrided exhaust valves, each measuring 1mm oversize for your Toyota Supra 2JZ engine. These valves are a key component for rebuilding or upgrading your engine's top end, directly impacting how efficiently your engine breathes.

The black nitriding process applied to these valves hardens the surface, making them more resistant to wear and heat. This is especially important for exhaust valves, which operate under high temperatures and pressures. The +1mm oversize dimension means these valves are slightly larger than stock, which can help improve sealing and potentially airflow when used in a performance-oriented rebuild. They are designed to fit the 2JZ engine, a well-regarded powerplant known for its performance potential.

When rebuilding your 2JZ, using well-made valves like these from Supertech is a solid choice. They are built to handle the demands of the engine and contribute to a reliable rebuild. Ensure you have the correct valve springs and retainers to match these valves for optimal performance and longevity.
