392 IAT (long) sensor virtually cured my heat soak issue

[Crush]

Thanks to the posts put up by mikeyChallenger Heat soak eats 20+ lb/ft of torque! and rayzazoo Mystery Grey IAT Sensor Connector - SOLVED!

My car is a dog in 85+ degree weather, esp with the A/C on, so I was really excited about trying the new 392 IAT sensor PN 05149279AB. It was $3.50 and plugged right into my gray connector and into my RoboFab air tube. Today was the real test as I go home for lunch, the car heat soaks, and I drive back in 90+ degree humid temps. The new sensor really made a difference I could feel. This is in the stock mounting location. Eventually I'll get the extension cable and relocate to the air box.

Thanks for the research guys as the heat soaking was one of my biggest complaints about the car. I can't wait to see if cooler weather performance is better as well.

(I wanted to put something with a "heat soak" subject in this section for exposure.)

I don't understand. You mean the longer extension one that came w some of the airhammers? Will this work w an 08 charger?

Sweet, I've read through the other threads and this looks wonderful. I'm going down to get one after work (or order it).

Wait so basically this is just longer and thus it gets the most accurate temp of the air actually entering the intake? So just the sensor and it connects right to where the current one does? Any adapter needed? Or just pn 05149279AB? Where'd you order it from?

Stopped at the dealer on my way home from work and got the new sensor. Drove home using torque to see 102 ambient air tmps and at one point then intake sensor read 180. Got home, swapped the new one in. Weather is supposed to be the same tomorrow so I'll test then to get accurate numbers for after.

Yes, browse through the other posts to get the full story, but basically the stubby stock IAT sensor heat soaks and gives false high reading. The new sensor with the extended arm put the tip in the middle of the airstream and gives a truer reading of the intake temps.

If you have the gray plug, the new IAT sensor plugs right in. Call your Dodge parts dept and see.......mine had it in stock.

Here are the two IAT sensors


Old


New

The new design insulates the wires and sensor better. I would compare the at idle temperatures between the two sensors and see which one rises more quickly and where they both stabilize at. Then compare this # with a thermocoupler reading like mikeychallenger did.

Great to hear this is working out. Also, I've got the parts to make a black to grey plug converter cable, I'm just waiting on parts to come in for the grey plug extension cable.

Does anyone know if 2012 cars are using this new long IAT sensor from the factory?

If I had to venture a guess I would say yes. The 2011 charger intake tube that I ordered to replace my 2009 tube (that has a resonator) came with the longer temp sensor installed in it already.

My 2011 has the new long sensor
