Hey guys, The 2008 GC has a different filter size from previous Mopars - it has 22mm threads! The Fram PH16 (or equivalent) is no longer used. Why change? I have no idea, but they did. I found this out the hard way today when trying to perform the first service. I went to O'Reilly Auto Parts and the computer brought up the same size as previous Mopars. I got home to figure out it was wrong. Here are the filters I have found which fit in case you have hell trying to find the right one like I did. Let me know as you guys find new ones, and I'll update the list. Mopar (p/n 04884899AB) Wix 57899 (O'Reilly) Bosch 3410 (Autozone)
As it turns out, there are many, many others. They just don't always pop-up as compatible with our Jeeps.
