Funny you should say something about intake temps. The other day on the way to work I checked the intake temp reading on my ultragauge. It was within a degree or two of the ambient temperature as measured by the car. The temperature was in the very low 60's. At 55 mph.The car is completely stock at this time. I will see if there is a manifold pressure reading available.
I wish I could figure out why they get the increased mileage. It does go against what I understand and have read. I have to drill a hole in the airbox-don't want to do that without some ensurance it will indeed raise fuel economy. A new replacement is over $125.00.
