Well got tired of waiting for mother nature to cooperate and stop pissing on my truck, and after a few emails complaining to her, she finally gave in and let off the rain for a few hours, only needed 15min and the carbon Cabin Air filter with Mopar cap was installed and filtering. Some people was asking if it really cut down on air flow once installed, and you can notice it, but its not that much. I actually find it cut the sound of the whirling fan down, you don't hear it as much. All in all, inexpensive mod that was easy to install, will keep the crap out of the cabin and should of been there when I bought the truck LOL. I guess the guy at Chrysler that made the decision not to provide one when you buy the truck brand new is a car guy like us and figured it was a mod we could install ourselves so we could play with our trucks.
