He made a comment or concern that he was running 40 degrees over ambient, and you said He is in Florida and it is 80 degrees there. I don't get how I'm being a smart ass! I hope he's not giving exaggerated numbers but I can only trust the information given. Clstec stated that he was running 20 degrees and higher and I believe he was getting those number when ambient temperatures where around 60 degrees. I think these are real numbers from people that actually have it. I don't have one and I'm on here looking for input from owners and not getting or trusting input numbers done in a lab from a manufacturer. Me a smart ass maybe😎

Lol your dynos in the USA read so high

Stick it in a dyno dynamics 4wd dyno and watch it lose 30hp

Then there's a mainline dyno, watch it lose another 10hp

Re: New aFe intake option coming...

Are you guys sitting in stop & go traffic when you see these IAT's? I didn't go through this whole thread, can someone post a picture of where the IAT sensor is located on the aFe? A very common mod on the later hemi's is relocating the IAT sensor.. This may be a simple fix for you guys seeing these crazy temps. If it's close to the stock location, start your jeep and stick your hand by the sensor... You'll feel hot at being blown directly at the sensor. That hot air is coming from the serpt belt and the rotation is blowing hot air directly on the sensor. I will take a high resolution thermal image of the engine compartment tomorrow and post it so you guys can understand a little better. I will be making a shield to bolt under the intake to force the hot air towards the front of the jeep.

There is a simple/easy fix for tricking the PCM from pulling timing.. That is wiring a resistor inline(100k ohm would do the trick), but I wouldn't recommend doing this if you do not know what you're doing. The IAT sensor is a thermistor, which basically means it measures air temperature by detecting resistance in the air. It is usually a two wire sensor supplied with a 5 volt reference wire.


As air passes over the sensor the resistance changes. This change in resistance affects the 5 Volts supplied to the sensor accordingly. Colder air causes higher resistance and higher signal voltage & warmer air lower resistance and lower signal voltage. The PCM monitors this change in the 5 Volts and calculates air temperature.

Wiring a resistor inline in the wire back to the PCM would fake the reading, and keep the IAT below the 90 dg. F mark so the computer never pulls timing.



Btw, 17whp from a CAI is very impressive no matter how you look at it.

Re: New aFe intake option coming...

@Jpeyatt
Stock iat sensor can be seen in the below photo. One thing to note is the stock direction of the sensor as well. The afe directions do not indicate a direction so after matching the stock position my temps got better.

Re: New aFe intake option coming...

The sensor must be turned so the opening with the blade is in direct airflow. Also check to see its fully installed...pushed all the way into the intake arm.

^ This! The insulated blue tip needs to be turned for direct airflow. Also, as Scott said.. Make sure it's fully seated in the tube. A little grease on the base will definitely help and prevent breaking the sensor. They can be a pita to get into the grommet dry.. After all, who likes going in dry?!

Re: New aFe intake option coming...

I would recommend an O ring grease or a grease intended for rubber as some greases would cause the grommet to rot or cause it to become hard and brittle

Exactly, one of the afe engineers actually told me it didn't matter... Smh.
At least it has a nice aluminum grommet. Good quality and locks the sensor in.

The minuscule amount of grease needed won't hurt the grommet, IMO.
