Sonatalover, you were looking for a case of filters. Ebay item #8072537110 One case (30) filters for $220 free delivery. That's $7.33 each. Just had my 07 Sonata SE oil changed at the dealer. Cost $35.71
My, O My, good subject for me here. When I bought my 2004 Sonata New, I talked the finance manager into 25 Free Oil Changes at no extra cost..How did I do this...? Quite simply told them that I was paying cash for the new car and that If I would let them finance the car for me, I wanted something in return ..25 oil changes with car wash each time, free painted royal blue stripping down the sides worth $110.00 and Embroidered floor mats with Sonata in them in silver thread on the gray carpetd mats. By the way I also got a Free Tank of gas and 6.5% financing thru there own bank..ie: great credit I have... All true Story! This is how you make car deals with dealers, you as a customer make the deal and they as the sellers accept your deal or you move on to another dealer...
I think the case fo filters are being sold by a Hyundai dealer's parts dept. I bought 6 Hyundai oil filters off Ebay from a Hyundai dealer. They are a genuine Hyundai part. It was a better price than buying them at the dealer in person.
As a side thought, I don't think you will have any problem with the Wix filters. They have a really good reputation for quality filters. No crappy aftermarket stuff.
