I have been buying AC oil filters for my wife's '03 Ecotec powered Cavalier at my local Chevy dealer for $5. I knew that was cheap and they finally caught on. The part number has changed and the price is now over $10! Amazing how a filter that appears to have less construction than a metal spin-on costs more! I will now use Fram
since these filters seem to be of identical plastic contruction as the OEM and don't have the dreaded cardboard caps. They are about $7 at wallyworld.
