Cooling....
The point about further cooling is well taken - obviously, if you could cool it further, it would result in more "gains".
However, just filling the TB with a liquid (any liquid) is not going to help - full, empty, the body will be at the same temperature, if you think about it.
If there was a way to circulate a liquid that was cooler than ambient thru it, you would have further gain, but there isn't.

sure there is -- would just require extensive modification, long story short maybe tapping the AC line and circulating the refrigerant thru the throttle body so the air would pass thru a 40 degree surface before entering the engine... but all the trouble and problems this would cause wouldnt be worth it im assuming because honestly how much gain is there to be had by passing air thru a cold chamber for the smallest fraction of a second.

if you had just straight water sitting in the TB, im sure it would start corroding, I capped off the top metal nipple with a little rubber cap to make sure nothing gets down in there. The other end I left open just because it's such a pain in the *** to get to. I'm not that worried about it, any moisture that MIGHT be in there would easily be evaporated off with the really hot engine bay temps.

Glenn (Razz1) came over to my house the other night and helped me perform this mod as well as the oil bypass mod and the difference is noticable. Espeacilly after I performed the oil mod. I would definitely recommend performing both of these updates as I am very happy that I did this..
Thankx again for your help Glenn. These are great mods that everyone should do to their car.

I changed the oil on my 2005 Ford Explorer 4X4 today. While I was under the hood I checked out the throttle body. The 4.0L V6 engine does not have any coolant lines attached to the throttle body.

I found a package with about 20 rubber nipple caps of various colors at O'Reilly's auto parts. Believed they were made by Moroso, so you will probably get 5-10 extra horsepower by using them!

Has anyone tried introducing a valve switch in the feed line as was mentioned above? I would love this mod for 90 degree track days, but probably need the warming in winter here. Has it been confirmed that the bottom line is the feed?

So why do people think the RX-8 needs to have hot coolant pumped through it in cold climates when the Ford Explorer's throttle body does not have any hot coolant going throught it.

Maybe the Ford explorer gets all of its intake air from under the hood. I don't know.
I assume Mazda went to the trouble of routing coolant to the TB for a reason and with all the flooding issues, I don't want to have idle problems and stalling when starting out on winter mornings. Once the engine is warmed up and running at 800rpm, it may have issues with condensation and poor fuel mixing when sucking in air that is -15F.

My 300ZX's throttle bodies did not have coolant lines on them (1992 model) and I lived in New Hampshire with that car for ~ 3 years....never had an issue...and that car was a complete cold air intake system.
Also it is mentioned "Starting out on cold winter mornings"..you coolant is freezing cold then after sitting all night, thus your throttle body is -15F too.
Sorry RX8Maine....I too am trying to figure out why MAzda did this....

all I know is that I live in Dallas/Fort Worth, texas and right now we are hitting 106 degree temps in the daytime, it's hotter then german sheiza **** here (LoL)
I don't know if my butt could feel any improvements with the TB bypass mod but I'm happy i did it. With 106 degree temps the last thing I want is my intake air to run thru one more ring of scorching hot temps. I'm not worried about the winter time here, it gets cold but not super-freezing-*** cold.
