Several locations sell crossover pipe heatshields. I run one from either 3800performance or the W-body store. I don't recall which. I also run some insulation scrap from last year'* Zilla CAI pipe around my INTENSE FWI TB adaptor and TB.

It doesn't matter much though. Think about how little heat the incoming air picks up from a hot TB at WOT air velocities. Thermal transfer is minimal compared to the rest of your internals.

How much of a difference is there between a hot TB adding heat to the air vs. an intercooler taking it away? Both are different temps than the surrounding air, only make contact at high velocity for a FRACTION of a second and an intercooler SIGNIFICANTLY drops temps; so why doesn't it work the other way with a hot TB to at least some extent? (maybe it'* not nearly as significant.

Is that what you're getting at? The intercooler has a much bigger surface area I guess too)

Surface area is the key. The intercooler'* surface area is enourmous in comparison.

This is one of the reasons TB spacers are such a joke.

I could be wrong but when I cleaned my throttle body, I found that coolant runs through the throttle body to keep it warm in the winter? Whatever the reason...Isn't the coolant going to be keeping it warmer than whatever intercooler you try?

All of us have coolant running through there. And I ran for a year with temp sensors all over the engine to see if it was worth plugging. My conclusion is the same as above. NO. Unless your car is nothing but a track-hound and not a daily driver.

This top end is going on my SLE within a couple weeks with all the sensors intact. I'll collect more data from that car.

What if we got back on topic?

I have my coolant blocked off from the TB. Drove all winter this way in New England and found no ill effects. Nor do I find any benefits.

My beer tree comment was made for a purpose. There'* no practical way to make a 3' TB spacer, nor any benefit to it whatsoever. Please read the explanations about heat transfer, surface area, and the time the air is actually in the TB above in this topic.
