Has no effect, at all.
As I tried to explain earlier, any change in fuel economy will most likely come down to specific MAF readings and how they are altered by the intake placement or choice of intake material. Venturi effect? Only so far as it alters the amount of air passing by the sensor. Can't make definitive claims unless and until you run a diagnostic and see what the specific difference is in sensor readouts.

Simply believing is not enough. Because buying an air filter for fuel economy is not a "one-size-fits-all" solution. Good for you if you see a fuel economy benefit, but most people on here are very skeptical of any result where there is no rigorous A-B-A-B testing. In other words... stock filter, aftermarket, stock, aftermarket, on the same day and hour, the same road, the same direction, in the same car, with all other factors controlled.
