Inconel Exhaust Valve Set

The Supertech exhaust valve set is constructed from Inconel material with a single groove design for high RPM applications. This set includes 8 valves, designed as a starting point for 1.8T cylinder head builds. They offer superior reliability and heat resistance compared to OEM stainless steel valves.

These valves are a direct replacement for stock valves and are suitable for turbo and nitrous applications. For maximum flow in high-performance builds, +1mm oversize options are available, though they require machine work. The single groove keeper design grips the valve shaft for enhanced security at high RPMs.
