Has anyone done this yet? If so post away

 

Can you describe what you mean exactly? When you mention this, my first thought is back to my Honda days where some would bypass the coolant line running through the TB to help "cool" the TB better than having hot coolant running through it. But this is just an assumption of what you mean.

 

That what they used to do in the B6/B7 Audi S4s as well.

 

Whoops didn't describe what I was looking for. Basically remove the two lines that run to the throttle body to help it de-ice in cold weather. I however live in the south where temps stay in the 80's + for more then halo the year. Heat soak is a problem for us. I've don't it in the past on prior cars with junctions,etc. just didn't know if anyone on the boards have tried it yet and knew the sizes of the hoses and what to purchase

 

I've not examined our 2IS TBs to see what the coolant passage does; but I'd have to assume it is a single passage way for the coolant to travel through. With a single tee, you should be able to bypass it altogether. Much benefit...doubtful; but it can't hurt (in your case).
