yes, interested in the results, you should also add in the data from the IAT sensor if you can collect it. A friend of mine has a Car Chip that collects whatever parameter you program it to. I looked at the IAT sensor and what I found was after about 5 minutes of driving, everything looses it's heat soak and the intake temps stabalize

I thought about this, but I don't have my own equipment to do the testing. I have a friend who has a Snap-On scan tool that could probably check the IAT, but I would have to get together with him to run the test. It would be interesting to see how much warmer the air gets as it is entering the intake.

one thing you dont have in your comments is how your going to simulate the heat shield for the K&N setup... any idea? One could be to go to Wally mart and get some poster board and make a shield that's close to the K&N's.

I currently have the factory fiber shield between the radiator and the frame. I am debating whether I want to remove it for the test or just put the sending unit right in front of this shield. If I remove the factory shield, I can do two tests, one with a mocked-up piece of cardboard or styrofoam, and another test without the shield in place to see how much heat is in that area from the engine.

I first ran this test on my Spirit. It has a single port throttle body with a heated air intake. A temperature sensor in the air filter box is supposed to control a valve on the intake that allows either heated air, a mix, or cold air only to enter the box. The cold air was pulled in from behind the headlight. That was an interesting test because I discovered that the temperature sensor was bad and I was only getting heated air into the air filter box. When the outside air was 35 F the temp inside the air filter box reached 135 F. I bypassed the temp sensor so only cold air was being pulled in and had similiar results to what I showed above with my truck. The filter air temp ran about 10 F - 20 F higher than the outside air. When I stopped or was moving slowly, the filter air temp would go up about 40 F higher than the outside air, but as soon as I started again, it dropped quickly.

One difference with my car is that it has a metal air filter box, sitting over the top of the engine. I recorded temperatures of 150 F after the engine was shut off. So I believe the metal conducts much more heat into the box.
