 Subject: Intake Question

Message:
Since cold air intakes are good, would there be any benefit in insulating the intake pipe with header wrap or something like that to minimize any heating effect from the engine compartment on intake air flow?? Anybody have any ideas on this concept??

I made a home brew w/K&N cone on the end and insulated the pipe. The key though with insulating it is to make sure you're sucking cold air to begin with.
I fabbed up a sheet metal heat shield that isolates the filter from the rest of the engine compartment, then I insulated that. Now when I pop the hood after driving for a few hours, the inside of the heat sheild is still cool to touch (just try and touch your air-hat or something on the stock intake after a few hours of driving).
I just picked up some HVAC pipe insulation from a local hardware store ... cost about $2.49 for the roll and all I needed was the one roll.
hope that helps.
PS I don't think header wrap would do much ... its too thin. Its only for high temp insulation, whereas the HVAC insulation is made to keep hot air hot and cold air cold (its about 1/4" thick).
