Have a 2008 T&C with the V6 and a 2008 Avenger with a 4 cylinder. Fram says CA9054 fits both. Was thinking of going to Wix for air filters at rock auto. I looked up the parts and wix p/n 42389 for the van and 49926 for the car. Why would the wix have two separate p/n's for wix and one for fram? I looked at the dimensions and the wix for the car is not as tall as the one for the van. I had a hard time closing the one air box, but can't remember which one. Maybe I have found the reason, Fram is taller than the wix for the car. Why the one filter for both from Fram?
