I just bought genuine Mopar filters for my Caravan from the dealer, because I bought 6, the guy at the parts counter gave them to me for trade price, which came out to $2.35 per filter plus environmental fee of $.50, after tax, total was less then 3 bucks a filter. These are made by Wix as well.
You can also get the Napa Pro Select filters which are made by Wix as well for around $3.45 a piece from any Napa store. Same thing with Carquest's house brand, these are also made by Wix and are less then 4 bucks a piece.
