Ferrea Honda D16Z6/Y5/Y7/Y8 27mm 5.46mm 115.95mm 22 Deg Flo +1mm Super Alloy Exhaust Valve- Set of 8

These Ferrea exhaust valves are made from a super alloy, a material chosen for its ability to handle the high temperatures and stresses found in performance Honda D16Z6, D16Y5, D16Y7, and D16Y8 engines. Each valve measures 27mm in diameter with a 5.46mm stem and a total length of 115.95mm, featuring a 22-degree face angle and a +1mm oversizing for improved flow.

The super alloy construction offers better heat resistance and durability compared to standard materials, which is crucial for exhaust valves that endure the hottest gases exiting the combustion chamber. The 22-degree face angle and the +1mm oversizing are design choices aimed at improving the valve's ability to seal against the valve seat and increasing the flow of exhaust gases out of the cylinder. This set includes eight valves, enough to replace all exhaust valves in a D16 engine.
