Has anyone heard about a wrap for CAI? Like the ones they use for the headers! I saw a pic here, that a turbo S2k had a wrap in the intake...If so does the wrap give you any gains? because your intake will be cooler, that means that you will have colder air inside your engine, would that equal to more HP?
Yes. The cooler you keep the intake charge the more power you get. Roughly 1% per every 5 or so degrees F.
The issue is that the intake charge doesn't spend a lot of time in the intake, so the heat transfer is minimal. Just by wrapping the intake you may not notice much, but combine that with an intake manifold insulator from Hondata and you would definitely notice a difference.
Thermotec sells a corrugated wrap that can be applied easily in a spiral fashion. If you are cheap, just about any insulating material that will stand up to at least 220 degrees F will work fine. I've used a foil-covered bubble-wrap material that is used as supplemental attic insulation and it works great. Was a little hard to apply, but with some foil tape it went on and looks OK.
Header wrap would do just as good of a job keeping heat out as it does keeping heat in. It is just an insulator. However, it would be better to have reflective surface, like the Thermotech tubing. Here is a picture.
Originally posted by SC-SUZUKA How much was the Thermotech tubing? was it hard to install?

It was really easy to install. It is like a dryer exhaust hose, except it has insulation. I just removed the top part of the CAI and slid the hose over the bottom and top pieces. It took about 15 minutes (including drinking a beer). I bought the tubing from a friend, but he bought 10 feet for $100. It takes about 3 feet.
