Supertech Toyota 4AGE 16V Black Nitrided Exhaust Valve - Set of 8

Supertech is known for making well-built engine components, and this set of eight Black Nitrided Exhaust Valves for the Toyota 4AGE 16V engine is a prime example. If you're rebuilding the top end of your 4AGE, these valves are designed to handle the heat and stress of the exhaust side. The black nitride coating isn't just for looks; it adds a layer of hardness to the valve face, which helps resist wear and can improve sealing over time.

These valves are a direct replacement for your stock units, meaning they fit right into your existing valve seats and guides. The black nitride treatment also makes the surface smoother, which can help reduce friction as the valve moves. This attention to detail in the coating and material choice means you're getting a part that's built to last and perform reliably in your engine.
