count me in on the spacers

hmm. ya tuff call..
Outlaw Engineering does not feel that bypassing the throttlebody coolant passage is a very elegant solution to throttlebody heat for many users. This often leads to rough idle, increased fuel consumption and possibly higher emissions. Many TB's contain thermosensors that would never reach operating temperature. It is similar to running an old carbureted vehicle with the choke all the time. Also, there truly is the possibility of ice formation in the TB during the colder months without this system. With the addition of an insulator, the vehicle can operate as it was meant to and the intake will remain cooler.

Im with him on that one. I ask autozone last year because I notice that the throttle body was hot from the coolant running through it. They said if you bypass the coolant from going to the throttle body that would make the car idle high b/c of temp sensors in the TB. And that also leading to more gas consumotion and might even trip a code, but the air would run cool before entering the intake manifold. LOL. Not something I would take a chance with. Unless you got an older car without the ECUs.

Thats a good idea. we should all order them lol... I did notice on my car that the intake manifold and throttle body get really hot, too hot to touch even a while after the car has been off. that probably isnt to good for power. maybe its cause the manifold goes right over the top of the engine and then the header....but if its insulated from the block it might stop a good ammount of heat from transferring.

I have a Ford Probe which has popup lights like the Supra does. One thing I did to keep the engine bay cool and keep my manifold cooler was take the headlights out and put foglights in for replacement. Looks good on a Probe plus keeps air running in the engine bay to keep it cool. This is a good mod if u like the look and u dont have a custom vented hood. I also cut two 2" strips out where the hood and windshields join or where the weather striping is for a constant flow. Believe it or not, not alot of water gets in the back of the engine bay.
