This comes directly from the Mac Performance site on their cold air intake systems:
Note: Independent Dyno test have shown that on modular motors 2V & 4V, by just removing the stock air box, without adding length in front of the mass air meter on normally aspirated motors, you will lose H.P. and TORQUE.
