Supertech Mazda/Ford Duratec 2.0L/2.3L Inconel Exhaust Valve - +2mm Oversize - Set of 8

Crafted from Inconel, a high-nickel alloy known for its exceptional heat and corrosion resistance, these Supertech exhaust valves are built to handle the demands of performance engines. This set includes eight valves, each measuring 2mm larger than stock, designed to increase airflow into the combustion chamber for improved performance. The Inconel material is crucial for exhaust valves because they experience the highest temperatures in the engine, and this alloy maintains its strength and integrity under extreme heat, preventing valve distortion or failure.

These valves are a popular choice for builders working on Mazda or Ford vehicles equipped with the 2.0L or 2.3L Duratec engine. The +2mm oversize design means they will require matching valve seats and potentially porting work to take full advantage of the increased flow potential. If you're rebuilding the top end of your Duratec engine and looking for components that can withstand high cylinder pressures and temperatures, these Inconel valves are a solid option. They are well-built to ensure consistent performance and longevity in demanding applications.
