Exhaust valve 3.8ltr W/A 1.11/16'' dia

By working closely with the UKs largest valve manufacturer, our finished valves are some of the most refined available today. Manufactured from single piece steel forgings, they undergo numerous machining operations, nitriding and grinding before ‘superfinishing’, a process which gives a mirror-like appearance. The end product is a valve that not only looks visually stunning, but also has increased service life and reduced frictional properties – ideal for extracting additional performance.
