Supertech Ford Duratec 2.3L Inconel Exh Valve +1mm OS - Single (D/S Only) (6mm Stem w/Tapered Tip)

This is a single Supertech Inconel exhaust valve designed for Ford Duratec 2.3L engines. It's a +1mm oversize valve, meaning it's slightly larger than the stock valve to potentially improve airflow. The valve has a 6mm stem and a tapered tip, which is a design feature that can help with sealing and performance.

Inconel is a high-nickel alloy known for its exceptional strength and resistance to extreme heat. This makes it a solid choice for exhaust valves, especially in applications where temperatures can get very high. The +1mm oversize dimension is important for rebuilding or modifying the cylinder head, as it requires a corresponding increase in the valve seat size to ensure a proper seal. This specific valve is for the driver's side (D/S) application.
