Supertech Toyota 4AGE 16V Black Nitrided Exhaust Valve - Single (Drop Ship Only)

The black nitriding treatment on this Supertech exhaust valve for the Toyota 4AGE 16V engine is a key detail. This advanced surface hardening process significantly boosts the valve's resistance to wear and heat, which is crucial for an exhaust valve that handles high temperatures and combustion gases. It’s a well-built component designed to keep your engine running smoothly.

When you're rebuilding the top end of your 4AGE, using valves like these can make a real difference in longevity and performance. The nitriding process creates a harder surface layer that helps prevent pitting and corrosion, ensuring a better seal and more consistent operation over time. This single valve is a direct replacement for your stock exhaust valve, making the installation straightforward if you're already working on the cylinder head.
