449-7113: Exhaust Valve Rotocoil

An Exhaust Valve Rotocoil is a spring-loaded device that is installed on the top of the exhaust valve. The Rotocoil causes the valve to rotate slightly each time it opens and closes. It helps to distribute the heat load evenly across the face of the valve, which helps to prevent it from wrapping or burning. Attributes: • Improved performance of the engine by reducing heat • Rotates when loaded from 785 N starting load to 1763 N under 900 IPM • Prevents the valve premature failure • More durable for longer periods Applications: This Exhaust Valve Rotocoil helps keep the spring in place and rotates the exhaust valve in a cylinder head to distribute the heat transfer evenly across the valve face.
