I went to NAPA today to get a new air filter for my Mustang GT. I ordered the NAPA GOLD. I opened the box to check and to my surprise it was made of a white filtering material with a black rubber seal! It did have a made in the USA printed on it. Also the stamping of the black seal was terrible, with a lot of shredding flakes of material. The pleats were not very good and a lower count than my previous yellow and orange WIX. The NAPA salesman told me that he guaranteed that it was a real WIX filter. It really looked exactly like a Champ filter. I told him no thank you and cancelled my order. So either WIX is no longer making the yellow and orange air filter or NAPA has changed suppliers. What do you guys think is going on?
