This might be a dumb question, but how does the P2R TB spacer add power? Why does adding a 3/4" space in between the intake and TB add power and increase gas mileage? Just curious, I like to know how things work. I've been doing research on this site and this seems to be the best first mod for my 07 Si.

UUUMMMM YYYEEAAAHHHH THE PLENUM...THAT WHAT I WAS GOING TO SAY

Plenum may refer to:

* the antithesis of a vacuum; in other words, completely-filled, positive-pressure space.
* the pressures slightly above atmospheric, usually inside air or gas systems as the result of the action of fans or blowers. The plenum is measured in small units of pressure such as pascals (Pa) or ounces-force per square inch or millimeters of mercury.
* a legislative meeting in which all members of the body are present and voting. Frequently this is used to refer to a full meeting of a Communist Party central committee. Compare to quorum.
* a second set of bellows in devices such as hand or foot pumped organs with a weight on the top which acts as an air reservoir.
* Plenums in buildings are enclosed spaces that are not for human occupancy, but are often used for heating, ventilating, and/or air-conditioning equipment and airflow, and for other equipment such as cables, piping, and luminaires. 'Plenum boxes' or sections are portions of HVAC air handlers or terminal units.
* Plenum cable refers to structured cabling permitted under building codes for plenum spaces. Plenum rated cable has slow-burning, fire-resistant casing that emits little smoke
* Plenum filtration, a method of aquarium filtration using a deep sand bed with a gap below it.
