ya dont plug them at all the cooler air will get in there
i think

 

i did this mod...i felt the short hose after a while of driving....thing was HOTTT....i'm thinking about heat wrapping it

 

Does this only work with 2005 models?

 

Yes, I believe only 2005's have the engine coolant running through the TB...

 

what kind of piece did you guys use to connect the hoses??

 

Can anyone confirm this does anything with IAT
readings before and after the mod?

 

yea i got an 07 and i dont have ne tubes i was pumped to f*ck with my car too lol

 

" I took some temperture readings before the bypass was installed. With the engine coolant running through the TB the top of the TB was approximately 165 degrees. The bottom side of the TB was close to 180 degrees. The coolant lines themselves were about 190 degrees. Now with the bypass in place the top of the TB was only 93 degrees while the bottom was 130 degrees. So the throttle body is MUCH cooler! So in theory there should be a performance gain..."

Hey wont coolant spill out once you pull one of the hoses off???

 

Maybe a temp controlled valve that allows coolant to flow
thru the TB during the winter when lets say the ambient
temp is below 40 degrees and by-pass the TB when temps
are above 40 degrees. Now that would be a good TB coolant
by-pass mod I could live with. Factory function cold weather
and performance function warm weather.
I dont have an 05 but rather an 07 with no TB heating.
I hope mine dont freeze in cold weather.
Maybe Ford found out that the S197s didnt really need TB
heating in cold weather on the 4.0 V6.....
