I'm interested in results also, but while we are waiting I might as well say something atleast somewhat useful.
Cold air = denser = more oxygen = more power.
Hot air = opposite. Our intake is ingeniously placed right next to probably the hottest part of the motor.
There are three different types of heat, radiant, conduction, and something else.
Plastic resist heat, metal absorbs and conducts heat.
Stock intake is a ram air directing flow directly into the throttle body. It's sn enclosed system not allowing engine heat to be sucked in. the air flow passes through quicker the the engine heat can heat up the stock plastic, therefore remaining cool.
An open element sucks in all that wonderful heat. An aluminum intake gets really hot and passes more heat through. Also on open element you lose ram air.
An insulation wrap is good on headers because it holds heat in. not sure if it would be useful on an intake. Should probably look into radiant heat wrap. Might work better.
Probably the most effective set up would be a plastic joez, header wrap, and a heat shield on the headers. Also header wrap causes exhaust gasses to travel faster through the exhaust making the car more efficient. I lost my original train of thought, but hopefully I covered enough for this post to make sense.
