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

Crafted from Inconel, a high-nickel, high-chromium alloy, these Supertech exhaust valves are built to withstand extreme temperatures and pressures found in high-performance Audi and Volkswagen 1.8T 5-valve engines. This material choice is crucial for exhaust valves, as they are exposed to the hottest gases exiting the combustion chamber, often exceeding 1000°F (538°C) and subject to significant thermal stress.

The Inconel alloy offers superior resistance to oxidation and corrosion compared to standard stainless steel, which means these valves will maintain their integrity and sealing ability under demanding conditions. This is particularly important for engines that see frequent track use, aggressive driving, or have been modified for increased power output, where stock valves might fail prematurely. Each valve in this set of 12 is precision-machined to meet exact specifications, ensuring a proper fit and reliable operation within the cylinder head.

When rebuilding or upgrading the top end of your Audi or VW 1.8T 5V engine, especially if you're pushing the limits of performance, these Inconel exhaust valves are a solid choice. They are designed to handle the intense heat and stress, contributing to the longevity and reliability of your engine's valvetrain under high-load scenarios. Ensure you have the correct valve seals and guides for your specific application when installing these performance components.
