Standpipe - keeps the filter full of oil. Not sure how much that matters other than making a bigger mess changing oil. lol. Apparently they decided it was not needed since they changed it on later ones. Short ones can use long or short filter.
I got a case of the long wix filters I scored on a RA closeout a while ago. Can use them on all the mopars I have. Today again rear rotors and brakes on the cobalt. Man that car eats brakes.
