Removal of airbox snorkle-BIG MPG! UPDATE 4.0!

To be technical, the ECU dictates the amount of fuel used as it relates to the amount of O2 in the air. Since warm air has less O2, the ECU reduces the amount of fuel. The stoich mix (for arguments sake, lets say its 14.7:1 O2 to fuel ratio) is always maintained by the ECU.
So cold air = more O2 = more fuel used.
warm air = less O2 = less fuel used.

Mmm....well, its not that straight forward, but you are basically correct. It is a looooong answer, which I do not currently have time for, but search terms like "pumping loss(es)" and/or "throttle plate", "stoich mix" along with "WAI" if you want to do some reading up on it.

It is a function of the engine RPM, the amount of air flowing past the MAF Mass Air Flow Sensor, the temperature of the intake air, the temperature of the engine (coolent), The position of the throttle plate and the change in position of the throttle plate if the gas pedal is moving, the readings off the two Oxygen sensors in the exhaust, Intake valve timing (VVTi), and finally if the AC is running or not.
That's what we mean when we say it is complicated.

For people that are worried about removing the snorkel and having the bottom of the air box exposed. I've found that the snorkel from a stock tC air box will fit. Its shorter and the opening sits right in front of the battery.

Cost me $1.99 and fits the opening perfectly. I already posted more info (SKU, etc) in this thread, so I wont do it again.

Hate to sound like a noobie (I never messed around under the hood) But could you theoretically remove the whole air box assembly and just stick an intake filter over there? If only that VSV connector wasn't in the way
