The EPA has done studies and found out that a dirty filter affects power not FE

But changing out the OE tiny little air tubes for the cold air intake vast gaping cavity vastly improved airflow. So more air means better volumetric efficiency. And if you P&G, more power means getting to speed sooner, which translate to more gliding and less pulsing.
