OEM A/C Compressor Pulley for Infiniti FX/QX 5.0L models. 

Located on the front of your engine, the idler pulley is responsible for guiding and maintaining tension with the drive belt. As the bearings in the pulley wear, you may begin to experience a high pitch squeaking or squealing. Over time this may result in complete bearing failure, causing the pulley to lock up and break the belt.

Ensure proper function with this genuine Infiniti replacement. 

Fits:

• 2009-2013 Infiniti FX50
• 2014 Infiniti QX70 (5.0L V8 Equipped Models Only)
