please explain the copper isothermal option again... how does this dramatically decrease the temps?...i would assume the coolant still flows through the throttle body, this gasket is used to keep some of that heat away from transferring into the plenum, right? if so, the valve would be a better option, only one would have to monitor its position accordingly for weather...
also, the 1/2 plenum spacer...does this work with the stock strut tower bar with an icreased strut tower bar spacer? (or are the studs that fit into the stock strut tower brace not tall enough?)...
I think i'm in for #7...when will the GB begin?
Thx

Also, the 1/2" spacer doesn't accommodate the stock strut bar. the 5/16" does.

+1 like Matt said.
Get the 5/16" Iso Thermal plenum spacer (no copper). If you drive to Montana in the winter get the Copper TB heater, otherwise it just doesn't get cold often enough in Ca to mandate the Copper.
The Copper TB heater is neat little device though. That thing really works!
When you put it on, the TB is clearly hot and the Plenum is clearly cool...

Great addition to the Motordyne Engineering product line!
I'm sure the drag, road, and autocross 350Z/G35 racers will appreciate these modifications. (lowering temperatures (prevents heat soak from happening as quick as it did before) and adding power (by increasing airflow))

(i know it wouldnt take much heat to prevent it from freezing-any other implication for the coolant line through there?)

I think I'll be down for the group buy. I'm still trying to decide on what size spacer to go with, depending on if the strut bar will fit on the 1/2".
If the stock strut doesn't fit with this spacer, I'm guessing I can go with the Crawford or APS strut bars?

So bang for the buck should i be looking at this over the cast crawford plenum???
If you only did it for the "buck", the answer is Yes.
If you only did it "bang for the buck", the answer is Yes x 2.
I know that must have pushed some buttons out there.

Thats the one question that will always stir up a fire storm, but if the question is asked, I must answer truthfully.
Putting on flame suit now!

G35's don't have a strut bar, but I use the hood spacers when tracking.
