Wrapped intake tube

[Andrew426]

I have a big roll of silver roof insulation (thick stuff with metal fibres through it) sitting in my garage and I have been thinking of wrapping my intake tube in the stuff to deflect radiant heat off the exh. manifold and also insulate it from ambient engine bay heat. Has anyone else tried this, or anything like it? has anyone noticed any benefit from something like this??

I haven't tryed it, but it wouldn't hurt. Won't make a MASSIVE difference because as i understand it, the air travels up the intake pipe that quick and constant, that it doesn't have time to get so warm that it affect's the performance of your car in a big way.

But hey, the heat wrap wouldn't hurt. Try it.

All it will do is make the pipe hotter as none of it is exposed to the air.

The intake air doesn't get hot enough to warrant insulating the intake pipe.

Yeah just after I posted it I was thinking how hot the intake plenum gets when the car is running, so wrapping the tube isnt really gonna help much.

I reckon it's one of those things, that if you could do it and it worked just like that - your car would have it out the factory.

I'm going to put my money on the "it's moving so fast it hardly has time to warm up" theory. Where you draw the air from in the first place is more likely to matter.
