All I know is that it is 650$ cheaper than a ipd plenum or rss plenum, what ever you want to call it. It is the same thing with factory parts and I think better because the abs plastic will not hold heat like a metal piece will. There are some real nice midrange gains on the ipd piece. I am not pushing ipd but the results seem great. I was hesitant from there price but I think for 260 I can manage. My .02

I just got off the phone with pedro's garage and I may have to pick one of these up for my 3.4 I will dyno it before and after. Gimme a week or so and it will be done.

This is similar to the intake manifold "turtles" that became popular on the Mopar Magnum engines. Basically, a small pyramid bolted to the flat bottom of the intake manifold to help direct air towards the runners. Multiple designs are offered based on RPM range.
These have been independantly proven to add a couple hp.

I'll second that. It basically allows a stock plenum to do what the IPD one does. That said, I have an IPD with a 3.4 throttle body bolted onto my 2.5->2.9 and I do think that it made a difference, but Pedro's solution looks just as good (and cheaper).
