Supertech Mazda MZR / Ford Duratec 2.0L/2.3L Inconel Exhaust Valve - Set of 8

If you're rebuilding the top end of a Mazda MZR or Ford Duratec 2.0L or 2.3L engine, these Supertech Inconel exhaust valves are a solid choice. They're built to handle the extreme heat and stress found in performance applications, especially if you're pushing the limits or dealing with boosted setups. Inconel is a special nickel-chromium alloy known for its exceptional resistance to high temperatures and corrosion, making it ideal for exhaust valve duty where temperatures can get very high.

This set includes eight valves, enough for a complete engine. The material choice means these valves can withstand prolonged exposure to high exhaust gas temperatures without deforming or degrading, which is crucial for maintaining engine performance and reliability over time. They are designed to be a direct replacement for your stock valves, simplifying the installation process for your mechanic.
