They argue these intakes deliver the air to the engine more efficiently while carrying a greater volume of air. Dare I say, high flow filters do most of this work.
High flow filters do nothing. The air intake MIGHT do something, but without pressure drop testing who knows.
A quick and dirty test would be to measure the maximum output from the MAF sensor, if it has one.
The throttle body is likely to be the greatest restriction.
