Not trying to be argumentative, just correct the whole "bigger volume" theory. The extra volume is at best a side effect. You could slightly decrease the main body of the plenum to counter-act the volume increase from the spacer and you would still see a gain.

I pretty much agree with this.
well put.
there is an increase in throttle response, however minute it may be. your jumping analogy was a good one, too. too bad I can't rep you.... not that it matters.
consider this a +1.
