Ram air busted: because it does not exist, for the following reasons:
- Air is incompressible at any automobile speed (I.e. speeds less than Mach 0.3).
meaning that the kinetic energy of the air cannot be used to compress the air and
raise the static pressure.
- The “ram air” nozzles commonly employed on automobiles tend to be the wrong
shape. A divergent nozzle is required for ram air. Straight-profile scoops cannot
provide a ram air effect.
Select one of the two types of intakes, warm air, or cold air. Beyond that its just about
looks."

drop in intake air temp. That works out to about 1% for 30 degrees.
Cold air kits: Busted (sorta)

Makes you think twice about those K&N claims we all seen. Fascinating stuff.
