As you can see on my avatar I have a aftermarket intake on my taco. I need to get some insulation on the metal intake tube because it gets way to hot from engine heat and even with how pretty is is now, I dont like all that heated air going into the engine. The filter is seperated from the engine heat pretty well but the pipe gets very hot to the touch. Any suggestions? Thanks.

 

Nomex

 

really, never thought about that stuff.

 

I need to do some research to find the stuff I had used before. It was cable sheathing made from Nomex fibers encapsulated in a high temp silicone. You'd be able to slide it over the intake like a sock. They had larger sizes that the intake pipe would fit into, but I can't remember where I got it.

 

OK, McMaster-Carr has it, but not big enough to fit the intake. They do have Silica sleeving that may work even better.

Thanks! Never really thought of this stuff as a idea for insulation, thats why I love this site. Whats funny too is I use mcmaster carr and grainger for ordering stuff at work but always forget to look for personal uses.

 

Forgot to ask, do you know the insulating properties of the silicon, I'm not too smart in this area. Does it not transfer heat at all, or just little?

 

Speaking as a wildland firefighter who wares the stuff everyday, Nomex will do jack squat for what you need. Nomex is somewhat fire resistant but has ZERO insuluative properties. You would do as well wrapping a old t-shirt around your intake. The largest difference in intake temp will come from a highly reflective layer, rather then an insulative one. Something like Header tape would probably work well.

 

You mean somethign liek this, I found it in my earlier lookings.

I measured, even under light acceleration after idling more than 1 cubic foot of air moves through the intake every second. If that intake pipe is 3” diameter and 2 feet long you are looking at 0.1 cubic feet volume.

Even theoretical complete and total insulation of the pipe isn’t going to do anything measurable unless you belong to the ‘bad ass 200ci drag racing’ camp of thought

 

So what we are looking at is as long as you arent taking in hot engine air, which Im not for the most part, insulating the tube isnt worth the $$$, kinda like a TB spacer.

 

Right. You would be way better off isolating that filter into the fenderwell somehow. Now that would be cool! I bet K&N makes a flat cone filter that would fit in that area.

 

Yeah, its isolated pretty well from the engine right now, but with all that room theres plenty of ways to easily get some fresher cooler air to it.
