Rocker Arm Adjusting Nut, Febi - 2002, E21, E30, E28, E34, E24, E9, Bavaria, E23, E32, M10, M20, M30

This part is listed by BMW as BMW part number 11331744333 (11 33 1 744 333) and is described as the M6 hex nut used in the rocker arm on M10, M20, and M30 engines in 2002, E21, E30, E28, E34, E24, E9, Bavaria, E23, E32 models. Everyone knows that threads don't last forever. Repeated adjustments, loosening and tightening, will weaken and soften threads which could lead to the screw and eccentric loosening and the rocker arm falling out of position. New nuts give you that extra security from poor rocker arm performance.

This part is manufactured by an aftermarket supplier of European auto parts, including many engine components. While not carrying OEM status, this part follows the design of the original very closely and uses similar materials. An aftermarket part may even have the same TUV approval as its OEM counterpart. The brand may even be OEM to another manufacturer besides BMW. This aftermarket brand has a two year warranty - the same as Genuine BMW and OEM brands.
