Supertech Mazda/Ford Duratec 2.0L/2.3L Inconel Exhaust Valve - +2mm Oversize - Single (D/S Only)

This is a single Supertech Inconel exhaust valve, designed as a +2mm oversize replacement for Mazda and Ford Duratec 2.0L and 2.3L engines. These valves are specifically for the 'D/S Only' application, meaning they are intended for the driver's side of the engine. If you're rebuilding the top end of your Duratec engine and need a valve that can handle higher temperatures and stresses, this is a solid option.

Inconel is a nickel-chromium-based superalloy known for its exceptional strength and resistance to high temperatures and corrosion. This makes it ideal for exhaust valves, which are subjected to the hottest gases in the combustion chamber. The +2mm oversize design means this valve has a larger diameter than the stock valve, which can help improve flow and performance, especially if you're porting and polishing your cylinder head. It's a well-built component that's meant to last under demanding conditions.
