Fiberglass header wrap would definitely hold the heat in the intake and have a reversed effect on what you are trying to achieve. Header wrap is made to keep the heat in the exhuast manifold so it dosen't get out, which in turn keeps the overall temps in the engine bay down. They sell specific intake wraps that are a foil material on the outside and cloth material on the inside. The foil repels the heat allowing the intake tube to stay cooler. Thermo tec makes a great lace up one that I have on my SRI. The upper radiator hose comes very close and in some cases touches a SRI on the EP3. I used to not even be able to touch the SRI without the wrap. There is a small portion of the intake right before the silicone connector that I can touch to see how hot it is and it stays cool to the touch ever after 20-30 minutes of stoplight driving.RC000E said:You may see some result on a dyno, but then you may not. I think under certain conditions it very well make a difference. I have always wrapped my intakes with the header wrap left over from the header. I don't have dyno results to back up its use, but every little bit helps. Certain conditions where underhood temps get high, I am sure it helps. Every 10-11 degrees you can reduce intake temps, you get a 1% overall increase in engine output.
AEM's intakes are aluminum, which certainly doesn't act as a very good thermal barrier. Do it, it can't hurt, it can only help.
I agree the engine bay is near 300 degrees in some areas so protecting with wrap can't be to bad.RC000E said:I actually always use steel tubing for the custom intakes I make, then coat them with a ceramic paint. I then finish them off with the header wrap. It's always been good for 20+ degrees of reduction in intake temps on the hottest of days. The only downside is the the header wrap isn't reflecting as would a foil style thermal barrier.
Fact is the engine bay is hotter than intake air temperatures, so the header wrap is still functioning as an insulator. Touch a header after it has been running for 5 minutes. It's proof in the fact the barrier works both ways. Fiberglass is a good insulator in either situation.
Is that your EP3? My EP3 is a sleeper, but I am thinking of some outside tired looks, got to be a surprise.revtune said:Did you try a motorcycle shop? I work parts at one, and you can get foil tape. Any Honda/Kawasaki/Suzuki or Yamaha shop should have some. They'll probably have to order it, but it is available.
lol Black absorbs heat!!! White reflects...K2e2vin said:i have a short ram, but my intake pipe was getting hot so i decided trying to paint it black because i read on another forum black repels heat. i didnt notice a difference. after that i wrap foil around half of the of the pipe and made a foil air box(made from aluminum foil pans). the car felt a little stronger(ghetto test: before i was able to reach around 80mph on this back road, after the mod i was able to do 90mph) and ive noticed the intake doesnt get as hot.
