Well you could you give us the part number for the iat. I was on the challenger forum site talking about the longer ,does iat plug into 05 iat wire harness or does it need to be modded. So does the lx srt8 cai fit perfect, What year is the srt 8 cai you got. Help member out. I like to do this mod.

Re: Back to stock air intake

Chris, the part number for the IAT Sensor for the 392 Challenger is: 05149279AB. It plugs right into the existing plug on my 06 WK, but DOES NOT WORK on my 05 Hemi LX. Don't know if the 05 WK is the same or not. The plugs are the only difference. My plan for the LX is to hit a junk yard and find one that works, cut it out and splice it into the LX harness. For your info. the Challenger sensor is about an inch longer than the stock units.

The LX SRT-8 airbox has to be modified to fit, because on the LX it mounts on the other side where the battery is located on our WK's. The bottom has to be cut a little (hence the larger bottom inlet) to fit the contour of the WK fender well. The mount also has to be completely modified. If you use the LX SRT-8 intake tube (I did), you'll have to plug the stock IAT Sensor hole, which is right next to the throttle body on the LX's, punch a new hole near the airbox where the stock WK sensor is located, and also extend (you can see it in the pix) the length of the tube a little. IMO, if you don't have one laying around like I did, you'd probably be better off picking up a WK SRT-8 setup. Then there's no modding and it all bolts right in. My LX SRT-8 setup came out of an 06 SRT-8 Charger, but all the early LX SRT's are the same. Hope this helps.
