sometimes it might show up when you go to buy the oil filter that their are two different types, If this happens buy both, take both out and put them on a nice clean surface somewhere in front of their respective box and when you take the old one out you can compare the old one with the new ones and pick the one that fits your car, then once you're all cleaned up afterwards, you can put the unused one back in the box and then take it back for a refund, or as part exchange for an air filter, that's what i did the first time.
