Results have already been measured, and this does nothing.
The coolant is at ~180F running through a short section of the intake.
Anyone that thinks it's a beneficial mod is ignoring the 230F+ of the components all around the rest of the intake pipe or even higher heat of the exhaust manifold sitting a very short distance from the lower intake manifold.

On Sunday I will have quite a few RX-8's around so as they show up I will measure throttle body temps while they are hot and post them up. Some are bypassed (that circuit is thru my turbo now), and some are stock. My guess is that all of the throttle bodies will measure at 200-230F (give or take a few degrees). This mod is pointless.

2 Cents, Instead of using the bypass I just used the autobahn88 kit and connected the TB line from the coolant pump, directly to the rear housing as it got rid of a coolant line, and made things neater. my IAT are 3 degrees above ambient considering we have nothing on are car that measure the IAT post TB, this is a mod that we will never know if it works or doesn't, but for me at least it was a free mod so why wouldn't you do it

I would like to see these results. Not that I would reroute mine back to the TB. I really like not having to mess with the coolant to remove the UIM.
Where do you plan to measure from? Booster line nipple? Maybe you can get one from the service ports on the LIM too. That would be interesting.
