gas mileage
There are many sources on the hows and whys, and for a practical indication, get a vacuum gauge. Just remember the lower the vacuum, the more fuel is being used.
BTW, ANYTHING added to the intake is only going to RESTRICT airflow, and in an EFI engine, there's NO need to "swirl" the air!!!
I average 23MPG winter, 25MPG summer and have seen 30MPG on trips, and there's ALWAYS a few passing of minivans and SUV's in ALL my trips!
