Supertech Audi V8 40V Inconel Exhaust Valve- +1mm Oversize - Single

If you're rebuilding the top end of your Audi V8 40V engine and need to replace exhaust valves, these Supertech Inconel valves are a solid choice. They are designed to handle the extreme heat and stress found in high-performance V8 applications, especially if you're pushing your engine hard or dealing with boosted setups. The Inconel material is known for its exceptional resistance to high temperatures and corrosion, which is crucial for exhaust valves that endure constant combustion cycles.

These are a +1mm oversize valve, meaning they are slightly larger in diameter than the stock valves. This can help improve airflow into the cylinder, potentially leading to better performance, especially when paired with other engine modifications. The single valve listing means you'll need to order the correct quantity for your specific V8 40V engine, which typically requires eight exhaust valves. Supertech is a well-known name in performance valvetrain components, and these valves are made to fit right into your Audi's cylinder head.
