ok. early summer I got my intake hydro-dipped and i wanted a new IAT sensor. I went to stealer and they told me I had to BUY the complete intake tube to get the $4 sensor. so i just reused what I had.

other day i am over on lxforums and come up a huge discussion about the NEW 392 IAT sensor. and how it needs the GRAY plug to work. so i dig in a bit further and realize the gray plug is exactly what I have on my 07 4.7.
so more digging and find a pic of the new sensor.....go check my intake and sensor is simialr except length.
the discussion was around the MAYBE BENEFIT of having the sensor out in the MIDDLE of the tube rarther than near the sides so as not to be affected by the heat soak of the tube itself.
I cant tell you any performance benefits but there COULD BE SOME.
but I can tell you the sensor is the same diameter and worked fine in my K&N.
MORAL OF THE STORY: IF YOU HAVE THE GRAY IAT PLUG THIS WILL WORK FOR YOU!
05149279AB 392 Chally IAT part number $3.90 plus tax at my local dodge dealer.

sensors side by side; new one is the longer 392 one

new sensor in the grommet. my old sensor the tab sticking out bent all the way back so sensor was shoved in to about the tab. new part has much more rigid tab so i ended up cutting it down some but not all the way.
