Ferrea Audi J7A/ADU/VW PL/9AR 28.1mm 6.93mm 22 Deg Flo Rad Grv Stk 6000 Series Exh Valve - Set of 8

If you're rebuilding the top end of your Audi J7A, ADU, or VW PL/9AR engine, you'll want to make sure your exhaust valves can handle the heat and pressure. These Ferrea 6000 Series exhaust valves are built for that kind of work. They're designed to fit right into your cylinder head, replacing your old, worn-out valves with something much more robust.

Each valve in this set features a 28.1mm head diameter and a 6.93mm stem, with a 22-degree seat angle. This specific design helps them seal well and manage exhaust gas flow efficiently. Ferrea uses strong materials in their 6000 Series valves, making them a solid option for engines that see regular use or are being built for improved performance. They are well-built to resist wear and deformation under high temperatures.

This is a set of eight valves, covering all the exhaust ports for a typical cylinder head on these Audi and VW engines. Make sure to check your specific engine's requirements to confirm these are the correct valves for your rebuild project.
