Not a bad thing, but I say its not worth it. Especially in a area that gets cold for 1/3 of the year.

I did it, but Im revered mani. So it saved having to run coolant lines to the tb. Its a good cheap mod though, no $ spent just remove one hose and loop the other hose to the nipple you removed the hose from. I dont think youll have problems if it is coll where you like, not like your tb is going to freeze up b/c there isnt hotass coolant going through it.

you shouldnt have any issues... mines been converted for a year or so now and no issues yet! i just re routed the one hose and used some vaccume caps from autozone to block off the other passages... it looks much more clean that way imho fyi i did mine when i did tgv deletes, p&p mani and the grimspeed thermal spacers

Ive been running mine for about a year and it does make a difference. Its not a big power adder but it helps keep the air going into the engine cooler. Ive read about people running this up in alaska and having no problems with thier TB getting tuck open due to the cold weather. Even if it is, let your engine warm up to normal operating temperature, engine temp > ice. It is very easy to do and super cheap, all you need is some hose, caps and a brass coupler fitting from homedepot or lowes ect.



In the picture you can see 2 red caps on either side of my TB where the coolant lines once flowed, all you do is disconnect the hose from the lower passenger side of the throttle body and insert brass coupler into the removed hose (I believe it ws a 3/8th fitting) now place cap over nipple that you just removed the hose from. Now go to the drivers side of the throttle body and remove the hose followed by plugging the nipple that it was removed from. Last step simply complete the circuit and connect the open ended hose to the other side of the brass coupler. Tuck away nice and clean...WALLA. Throttle body coolant mod, I think in all I spent under $5 and 5 minutes install time.

In my picture you can see the lines running under the intercooler pipes and ontop of the block which replaces the pcv breather lines and connects to the turbo inlet all flowing to my cusco catch can, removing those 2 eyesore-ish soft and hard lines that ran on the tmic.

I think the theory behind it is heatsoak... I thought about it a bit today, and during an extremely hot idle coolant could actually cool the TB a bit.

This would only apply if temps at the TB were above 200*F...

the little caps were actually bought at pepboys in a variety pack, however they have them at home depot and hardware stores. You can prolly just print out that picture and say "where are these"

hi!
it seems to be a nice mod, even if you don't see any difference! I think it's very interesting if you do this mod and add the phenolic intake gasket to reduce the air temperature ! then the knock should be reduced and you should keep your engine ok!

I also use the bypass for my water temp gauge as coolant always flows through it.
