Insulating intake tube?

Would it do any good to wrap the intake tube from the filter to the throttle body in header wrap or some other type of insutaltion wrap to keep it from getting as hot from under hood temps?
 
By the time it's all said and done you should just do water injection or windshield wiper injection because the cooling benefits will be MUCH greater then ANY wrap.
 
I wouldn't worry too much about wrapping the intake tube. I read a couple years back where a company that makes Cold Air Intakes (sorry, can't remember for sure which company it was) did testing on steel, aluminum, and plastic CAI tubes to measure air temps and see if there eally was any significant change in air temp do to a hot tube.

The results showed almost NO difference among all setups tested. They attributed this to the fact that the air is travelling through the intake tube at a high enough velocity that it simply doesn't have time to get heated up by the hot intake tube.

It is the same thing as removing your thermostat from the cooling system. The coolant is constantly circulating as fast as the pump can move it and does not spend enough time in the radiator to remove enough heat.

So what it really boils down to, is that it has been proven that metal air intake tubes do not cause you to get a warmer intake air charge than plastic or pvc. So wrapping the intake tube would be a waste of time and money and likely look like crap anway. You would be better off wrapping the exhaust to keep the heat out of the engine bay in the first place.
