I have this weird idea.. arent the stock hoses better since plastic are better materail resists to heat? i mean why do you want to replace polish hose while they transfer heat easier, everytime i pop my hood and those polish hoses really burn..
agree?? specailly intake hoses u dun wan heated air in those hoses~
somebody correct me if i m wrong

i have replaced all my hoses to polish ..from elbow to intercoler pipe then ypipe, intake pipe. lookz nice but they burn ur hand/.. ouch

Sure, rubber insulates better than almost any metal.&nbsp But, if going custom IC, why use stuff (i.e. rubber) that flexes and makes you lose boost and consequently airflow?

Metal tubes have the advantage of a machined smoothness that rubber can't have. Smoother airflow=less turbulence= turbos don't have to work as hard to make the same pressure.

Rubber is not necessarily a heat insulator, it just doesn't get hot itself. But the air inside the hose is just as warm as outside. The rubber stays cooler, but the air doesn't.

The better choice would be ceramic pipes, since ceramics are some of the best heat insulators. The drawback to ceramic is that it's very brittle. But if you could make a ceramic pipe thick enough to not crack under normal engine motion.. now you're on to something.

i m doin this intake temp test with polish hose and wrap up foil rubber hose ..hopefully find some clues..
