Default CAI Temp

Has anyone ever used a scanner to see what the IAT is after installing a CAI? I used the one from work and compared the stock one versus my homemade cai and there was no difference in temp. Curious if anyone else has tried or if this is even a liable source of how well the cai is working?

Well what we call cai arent really cai they are more ram air intakes. To my understanding a real cai goes depper down in the engine bay and has a heat shielded vent to outside air. A cone ram air intake still can take in more air b/c of the shape and more exposed filter as opposed to stock but where the power in replacing a stock air hat w/ a cai is in the tube. No air baffles and alot less restricting than stock. If anyone more Ram savy than me has a better answer feel free to correct me thats just always how I understood it

yea to get a true CAI normally the filter is located closer to the bumper normally in the spot of a fog light or something. As well a lot of people will take header heat wraps and wrap both the exhaust headers as well as the tubing for the CAI which keeps the heat in the headers and keeps the heat out of the CAI. It is probably an effective way of measuring the temp of it but with the exhaust headers right below the piping for the CAI its gonna heat up just as much, the CAI for our trucks are just as mopar explained they just increase the amount of airflow more so then giving the engine colder air.

If youre all about temp wrap your headers and CAI piping with header heat wraps and that should make a tiny bit of difference

What is the style CAI you made? Open filter? If so, it's still getting warm/hot air from the engine compartment. True cold air, and cooler intake air charge, comes from having a system that takes the air from outside the vehicle.

okay well i do understand what yall are saying. havent built a heat shield for it, so it is just taking in the engine compartment air. for some dumb reason was thinking that the filter would make the air a little cooler. I get that more air equals more power, which is what i have now, but isnt more air and colder air better?

Colder air is more dense thus creates a better combustion.

okay cool. so more air is more power. but more colder/denser air is even more power because of the better combustion. Gunna build a heat shield today hopefully, and a ram air type deal for my cai. Would colder air make less mpg though?
