The valve spring washer ring for the exhaust is a crucial component for Citroën 11CV and HY models produced between January 1955 and September 1963. This part ensures that the valve spring assembly remains securely in place, which is essential for the proper functioning of the engine. Due to wear and tear, this ring may need to be replaced over time to maintain optimal engine performance. It is specifically designed to work closely with exhaust valves for maximum efficiency and durability, helping to keep your classic Citroën running smoothly and reliably.
