Genuine OEM Volkswagen Engine Roller Rocker Arm, part number 04L109417. This precision-engineered component is integral to the engine's valvetrain, converting the rotational motion of the camshaft into the reciprocating motion required to open and close the engine valves. It is situated within the cylinder head, interacting directly with the camshaft and valve stems. Made from high-strength metal, it measures approximately 40mm in length. Choosing a genuine OEM roller rocker arm ensures the correct material hardness, precise roller bearing tolerances, and exact geometry, which are crucial for minimizing friction, reducing wear, and maintaining optimal engine performance and efficiency.
