Did anyone notice on the dyno sheet that the stock intake was tested at 11:00 a.m. (a hotter part of the day) and the Injen intake was tested around 6:00 p.m. , a much cooler part of the day (colder air equals denser air and more oxygen). The temperatre change alone is bound to increase horsepower.
What do you think the power gained from the CAI unit versus the replacement of the filter element alone would be?

Thanks in advance for your time!
