Whoa! That is an big'ol obnoxious engine cover on the rear-wheel drive version of the Pentastar V6. Looks like plenty of clearance with the access hole for the oil filter though..
I know on my 2013 Grand Caravan, I like to pull off the engine cover at oil change time just to give everything a look-over. I pop the top off the air cleaner housing and swing it out of the way for better clearance around the oil filter housing on the FWD version of this engine.
