So I ordered a few oil filters from a "Kia dealer" on eBay. Today I went to the dealer in town and bought a filter to compare to the ones I ordered from eBay. The first thing I noticed is the W that is stamped into the baseplate is not the same. The pattern design that is stamped on the center tube is not the same. The lettering on the outside of the filter is far more finely detailed on the one from my dealer here in town. Also the square that outlines the drawing of the trash receptacle on the filter is not the same size. The one from eBay has made in Korea below there trash can drawing and the dealer one has nothing beneath theirs. These are the differences I noticed just by visually comparing the two. Oh, and the eBay filters came in a Kia motors box and all the ones I have bought at the Kia dealership have been in Hyundai boxes. These differences are enough for me not to trust the eBay filters to install on my car.
