Notes: Accessory Drive Belt Idler Pulley Adjustment Bolt Kit -- Air Conditioning Idler Pulley
This product was pretty good and was a better deal than purchasing from the dealer. Good quality and more accessories for your money.
When replacing your idler pulley make sure to purchase this kit. Perfect fit on 2004 Impreza (WRX included) and chances are one of your original parts will be extremely rusted or melted (as was my case).
