I ordered the K&N high flow one and was coming on here to let everyone know it did not fit in my powerwagon. It fit my wife's 1500 just fine, but I could not get it to go all the way into my 2020 2500 PW. The filter was too thick and possibly too wide at the end. It seems like the filter box tapers in the back.My 2022 came with a N95 cabin filter and it was very restrictive. Compared to the standard filter this thing was THICK! I've since replaced it with a reusable K&N cabin filter that i clean with every oil change just to keep the air flow flowing at its max.
My 2016 Ram Rebel had great AC till i realized it didn't come with a cabin filter.
