This is an OEM INA Idler Pulley, also known as the roller pulley or deflection pulley. The idler pulleys are known to be the primary sources for 'belt squealing'. The pulley is also encased in rubber which will crack over time. If left without service the rubber could fail completely, chucking the belt and leaving you stranded. Replacement is a very simple procedure and can be done anytime the fan is off the engine (belt replacement, water pump service, alternator replacement, etc). OEM replacement for BMW part # 11281720039 and 11281715630.

ADJUSTING PULLEY 11281720039 OEM

This item fits the following BMWs:
BMW 7 Series - 750iL
BMW 8 Series - 850i/Ci/Csi

This is an OEM MAHLE fuel filter that removes dirt and other particle contaminants from your fuel.

A clogged fuel filter makes it difficult for your engine to get all the fueling it needs. Filters commonly clog from a deteriorating gas tank, bad fuel, or other debris in the fuel system. A fresh fuel filter addresses many fuel related problems including surging, stalling, cold start issues, and poor performance under a variety of conditions.

Don't neglect your motor mounts! Most stock BMW motor mounts are fluid filled and the stiffness of the mount depends on this fluid. But over time the fluid leaks out and the strength of the mount is greatly reduced. A worn motor mount allows the engine to twist and shift around. The harder you're driving the more shift will occur. As the engine is moving around it can contact other parts in the engine bay - usually cooling related. The mechanical fan can hit the radiator; the A/C compressor can hit a radiator hose, the exhaust will flex and may break. Twisting of the engine can also lead to shifting problems as the transmission twists with it. There are countless issues related to worn or compressed motor mounts so don't overlook these as a regular replacement item (every 50,000 miles).

This mount is for the right/passenger's side.

This is a direct replacement for the factory motor mount for M62 V8 engines and M73N V12 engines.
