so some months have gone by since i did the by-pass to the throttle body coolant lines. its gone from cold to 100+ temperatures in this area. no changes good or bad to performance. i`m thinking it was kind of a useless thing. the only advantage is now its easier to remove the throttle body to clean it, which is not a bad thing :shiny:

i didnt even block the 2 ports off, its just a coolant cavity and you cant really see them up under there unless you get into the engine bay looking for them. i thought i`d post this to see if anyone had any conditions doing this good or bad.

the first time i cleaned it i think was around 40,000 or so, it was filthy and i`m sure had never been done. the last time was around 10,000 and it didnt look too bad really. you can check it just by pulling the cai off the frt and looking in. if its all black, wouldnt hurt to clean it. can of throttle body cleaner and some clean rags. :)

dont mean to jack your thread but your car blows!

"4.0 hp emblems" in your sig.


get a REAL car, get a REAL 4.0L V6.


just because its 4.0...dont mean its a 4.0!

thanks 05horse, i like your car too, even though its a stick. :D my emblems say 4.0 high performance, but ive run out of number of character spaces in the signiture so ive had to abreviate as much as possible.:) any more mods i`ll have to ditch the 06 for more space:hihi: but thank you for taking the time to read my entire sugniture :wavey

No temperature measurements were made, and "no changes to performance" is only by seat of the pants feel.

Ideally, you'd monitor intake air temps under same ambient air temps with and without the bypass and measure the effects actual intake air temperature under idle, part throttle, and wide open throttle.

In general, anything to reduce the temperature of incoming air will improve performance and efficiency and potency of combustion.
Running hot water through the throttle body will heat it up, and air flowing through it will heat up slightly. Not good.

Do the mod, it's easy to do; Ford did away with the bypass in '06, so even they agree it's not needed at least in most climates.

thank you for the in depth description! I went ahead and did this last night right after work. definitely was simple and gave me a chance to look at my new radiator cover shield thing while doing so hahah

on the 06 they did away with the nipples coming off the double metal coolant lines for the tb hoses. i thought about replacing that assembly but it was something like $100 for those little metal tubes so i`ll just stick with the bipass untill i happen across the new tubes somewhere else.

I should have one of those steel lines w/o the tubes from a '06 from a engine I parted out.
