Slight improvement over yesterday's test while moving, even better when stopped and idling. I will be posting a picture of the setup in my gallery. Since the uninsulated stock and K&N style setup had similiar results, I'm not going to run an insulated K&N style setup. One more test, then I want to provide a summary of all the tests showing the difference in temperature.
