i did not read it all because well, who has time for that but the part that did stand out was this

'What is a
Plenum Spacer? What is an Intake Manifold Spacer?
Some modern cars, like the
350Z and Scion
FR-S/Subaru BRZ feature a multi-piece intake manifold.
These Plenum spacers are sandwiched between the cylinder heads and the intake
manifold or sections of the intake manifold to create longer intake runners. The
lengthened intake runners enhance the volumetric efficiency of the engine which
translated into an increase in horsepower and torque as well as an improved
power band.
Of course, these
upgrades are a stopgap that offer a portion of the benefits offered by a
performance-oriented Intake Manifold, such as those offered by iPD
Plenum.
So in closing, if
you’re looking for a way to pick up a little extra power and enhance your
efficiency, a Throttle Body Spacer is an effective, inexpensive and
simple-to-install means to achieve that goal.
