I have been buying filters from rock auto for over ten years. I Service not only our cars but neighbors and friends. All of the filters I purchased were either clearance or deeply discounted. I had a small percentage of dented ones or some slight rust. All functioned without failure. Before we bash rock auto for having dented filters remember what you paid for them. $1.10 each, then just use them and don't complain. If I paid $6.00 for one filter, then it should be perfect. Rock Auto has been a very economical way to purchase auto parts. Not always just off the production line but function every bit as well as the sparkling new part for top dollar. It's all what you want, Rock auto has been my go to for parts. I won't send a set of brake pads back or complain because the box is tore up or dusty. I would use them just the same. My Ram Truck has been using Rock Auto filters for 10 years without a problem.
