Correct part (Mopar MO-349) but shipping method could be improved.
Size: 1 Count, Size: 1 Count
I received what I ordered, Mopar MO-349 oil filters. However, they were shipped in what looked like an oversized paper bag and the boxes that contained the filters were crushed (see picture). They should have been shipped in a small box instead of a giant paper bag. The filters look ok but I guess I'll know for sure when I try to use them. Plus 4 stars for the product. Minus 1 star for Amazon shipping.
