Engine Pro Nitro Black Perf Valves Set for Ford Navistar Powerstroke Turbo 7.3L 1994-2003
Our diesel performance valves are designed to perform reliably in the extreme conditions that exist in highly boosted turbo diesel engines. Bi-metallic exhaust valves are made from inconel and HNV-3 alloys and are stellite faced to operate under extreme heat conditions. Intake valves are made from 21-4N alloy steel. Both intake and exhaust valves are put through our proprietary five step liquid nitriding process, resulting in valves that are smoother, stronger and more corrosion resistant than traditional chrome plated stainless valves. If you have any questions, please message us.
