Supertech Audi/VW 1.8T 5V Inconel Exhaust Valve - Set of 12

Made from Inconel, a high-nickel alloy known for its exceptional heat and corrosion resistance, these Supertech exhaust valves are built to handle the extreme temperatures found in high-performance Audi and Volkswagen 1.8T 5V engines. If you're rebuilding the top end of your 1.8T and pushing its limits, or simply want the best possible durability for your engine, these valves are a solid choice. The Inconel material is crucial for exhaust valves because it can withstand the intense heat cycles and corrosive gases that pass through the exhaust port, helping to prevent valve seat recession and maintain sealing integrity over time.

This set includes 12 valves, enough for a complete engine installation on your 1.8T 5V. Supertech has a reputation for producing well-built internal engine components, and these valves are no exception. They are designed to be a direct replacement for your stock valves, meaning they fit right into your existing valve guides and work with your stock or upgraded valve springs and retainers. The material choice here is key; while stainless steel is common, Inconel offers a significant advantage in high-heat environments, making it ideal for turbocharged applications where exhaust gas temperatures can soar.

When installing these valves, ensure your valve guides are in good condition and properly sized. It's also a good idea to have your cylinder head professionally cleaned and inspected before reassembly. These valves are a critical component for engine longevity and performance, especially if you're tuning your 1.8T for more power. They are a worthwhile investment for anyone serious about the long-term health and capability of their engine.
