The idler pulley is only sold as an assembly from Infiniti. Their regular msrp is $146. Not sure if there is a cheaper aftermarket available. Kind of steep if you ask me. this will give you the exact part number for comparison.

If that's the part your saving a couple of bucks over msrp. Infiniti has it at $232.
