INA, the German engineering brand renowned for OE-quality engine components, presents the Rocker Arm 4220099100. This rocker arm translates camshaft motion into precise valve actuation, controlling the opening and closing of intake and exhaust valves to maintain correct valve timing and engine breathing. Built to meet or exceed OEM specifications, it supports reliable operation and reflects INA's commitment to engineering precision and durability. Suitable for select Mercedes-Benz applications.

Rocker arms endure constant mechanical load, heat, and lubrication challenges; wear can introduce valve train play, mis-timing, rough idle, or reduced power. Replacing with INA 4220099100 restores proper valve actuation, improves combustion efficiency, and helps prevent further engine wear. Part number 4220099100.
