Supertech - Inconel Exhaust Valves (Set of 10) - 2017-2025 Audi RS3; 2018-2023 Audi TT RS

Supertech sodium filled valves made of Inconel/Nimonic alloy offer a significant reduction in valve head temperatures that are required for today’s modern turbo engines.

A cooler valve improves the material strength and durability while allowing the tuner more flexibility and a wider range of spark timing advances. Combine that with an average weight reduction of 10% and there isn’t a cooler valve on the market

Valves play a critical role in any performance-orientated engine. Upgrading the valves in your VW or Audi engine increases reliability with slow forging processes, upgraded aerospace alloys, CNC machining, and heat treatments to withstand extreme abuse from high-powered race engines and daily driven road vehicles making beyond factory power levels. The power an engine produces is limited to airflow. As the smallest chokepoint in your cylinder head, performance valves are engineered to increase airflow by limiting turbulence created by valve stem obstruction and careful detailing of the valve head and valve angles.
