Yes, that is probably the best thing that the AFE filter. You know for kicks, we can do measurements on my car with the stock air intake vs. the AFE. Of course, that is when you have time!
We should do this and of course we can use your special test course!

On average:
Outside temperature was 71 F
MAF flow rate at idle was .75 lbs/min
MAF flow rate at 70mph was 4-6 lbs/min
Intake temp at idle was 80 F
Intake temp at 70mph was 77 F
As you can see, its only 6 degrees difference... wonder how much the AFE/DINAN/etc CAI kits really do... I'm almost certain the only gains is from the different filters that allow more air flow...
