My daughter and her husband, just married a few months ago, went out to buy their first car. I thought they made a great deal on a 2012 Hyundai Sonata. I was a little concerned at the GDI engine, and then got a lot more concerned when I saw that the previous owner had put a K&N air filter on it!
I tossed the K&N on the concrete and a bunch of crud came out. In my mind I'm saying, "Why?, Why???". (I'm one who believes that these re-usable air filters let too much dirt pass...) I offer to buy them a new paper filter. My new son-in-law is a great kid but not at all tuned in to mechanical things. So I get back with the paper filter, and after taking the air box apart a little more I notice that there is a second, "permanent" air filter inside the air box. It says "Do not remove" in English and Korean. Perhaps all is not lost? The second filter looked to be in decent condition.
Anyway, I put the paper filter in and hopefully they will get their moneysworth out of this ride. I hadn't seen a double air filter before.
