The 5 mm oil scraper piston ring is designed for vehicles such as the Citroën HY, 11CV, 15CV, and DS19. This component ensures efficient removal of excess oil from the cylinder wall during the piston's up-and-down movement. It prevents oil buildup and smoke development, contributing to better compression and engine performance. The oil scraper ring is essential for maintaining optimal engine operation and minimizes the risk of wear and damage. It is a crucial part for classic Citroën enthusiasts focusing on reliability and durability.
