Like I said, what HP do you gain from buying the IPD $800 Plenum over the 997 $70 Plenum? You're surly not going to get 15% more more HP with the IPD Plenum over the 997 Plenum and you're paying 1,045% more for that IPD Plenum. Let that sink in a bit 1,045% more then the 997 Plenum?
BTW: The 997 Plenum has an excellent outer radius on it's Y shape, it's not just a T shape.
Does this radius matter? According to Jake Raby it does.

The plenum alone isn't where your adding hp gain, you have to include a new larger throttle body. I not arguing one is better than the other, because i cant say, but before you start saying $800 you need to read up on what is needed to get the power gain.
The IPD vendor claims power gains in throughout the whole rpm range with most gains in the mid range.
Fabspeed is now selling the ipd plenums as well, another reputable porsche tuner, so that has to say something.
As i pointed out its a matter of opinion, as for worth.
