well i could dyno the truck at work and do all sorts of tests and put an end to this disscussion once and for all.
But you know what my air filter stays cleaner longer, i can feel a difference in acceleration between 45-75MPH range and my gas milage is so bad i don't even care anymore. My goal was clean air and deep water, and i already know my air intake is cleaner because my filter is still like new compared to before where it would be full of dirt after one dusty trail especially following other trucks.
