I assume that this data is from your truck and you didn't relocate your IAT sensor. Also, what temp thermostat are your running?

I wondered what temperatures the IAT sensor would be recording. It is a little higher than I thought it would be. Also, I wonder if the outside air temperature was cooler, if the temperature inside the manifold would be lower? Maybe the intake will always heat the air to the same approximate temperature. If that is the case, maybe the perfomance gains from CAI's is related to airflow efficiency through the tubing rather than air temperature. Sometime, I would like to run these tests with a scan tool and check the IAT temperature if that is possible. Thanks for posting the data, it gives me something to think about.

I would like to see some pictures of your engine compartment. I am interested in what your K&N setup looks like with the round filter.
