I ran the gutted airbox for two days and went back to the FWI. I did a little testing with my scan guage to see what the difference was with the intakes and the IAT temps. It was a very sunny day and the ambient air temperature ranged from 86 to 89 dergrees during all testing. The IAT temps with the airbox driving in heavy stop and go traffic was 113. Sitting at a red light for five minutes, the temp hit 120. While driving at 65 for 10 minutes, the temp never dropped below 96. I then switched back to the FWI and drove the same route. While driving in traffic the FWI was 98, sitting at the same red light the temp was 128 (higher than the airbox) and at 65 the temp dropped to 90. So, even though the FWI hit a higher temp sitting at a red light than the airbox, once moving the FWI was able to draw cooler air in quicker and had a lower temp than the airbox.
