No MAF sensor, its a speed-density system with a MAP sensor as are all Chrysler engines. So at least that's one way that a K&N can't hurt it...
But the inside of the intake manifold will get nasty from all the dirt that gets through the filter... it should be plenty obvious from the rest of the engine bay that while it may not be Tuscon, there still is enough dust in CenTex to warrant good air filtration.
In case you haven't guessed, I'm not a big fan of CAI kits and K&N air filters for street-driven cars. I used a K&N drop-in years ago, and while the engine lived to a ripe old age, the inside of the intake when I had it apart at one time convinced me to go back to a paper filter.
