Which air intake system?

Just common sense.... if an intake system is not properly insulated against the engin heat then it is not COLD AIR intake...just my personal opinion and please tell me if you know how it is COLD?
My stock intake air temprature (which is not open to engin heat) is higher than the out side temprature!!! IAT reads up to 145F, 30F or more than ouside temp...
I call this HOT intake

Placing the filter in an enclosure be it sealed or not does not remove it from the latent underhood heat. Air as all gasses is a lousy heat transfer medium. That is why beer is colder when cooled in an ice water bath than in ice alone. Because liquids, in this case the water around the beer and ice, is more efficient at removing/absorbing heat than air. Neither plastic or stainless tubes absord or shed heat well. Enough with the thermodynamics/heat transfer.
It is just marketing, marketing, marketing.
Hey this thread was dead for the past month and one-half.

Cold air intake...well, they used to be called fresh air intakes...the idea was to use outside air, which would be cooler than underhood air.
My Airaid intake tube is, in fact, hot to the touch after only a few miles. The factory setup was the same. I have some thin foil covered insulation that I am thinking about wrapping around the tube, and also covering the shroud around the filter with it to reduce underhood radiant heat transfer. Filling in the gaps at the sides af the shroud would also help, by keeping (or at least minimizing..)underhood air from passing through to the filter.
I agree..lesss restriction is where any gain comes from. It might be a few degrees cooler due to the free flow...less time in the tube. The factory setup has ripples and tubes/baffles.

My vote goes out for Volant. I have a 4.6 and with this closed enclosure set up, my truck sounds like its got a supercharger. You can literally hear the thing sucking up air. And plus, my Edge Programmer proves to me that the unit definitely works because I can see the temperature decrease in the air intake temperature from before and after. And finally, my Flowmaster 40 series got louder after installing this. VOLANT is the way to go
P.S. I had a K&N drop in air filter along with the silencer being removed prior to Volant. No comparison what so ever.

I have the edge evolution on my 5.4, how do I check the intake temps?

Do you have the latest update? If you do, then go into the display and it should be there...

I just got a volant intake, I didn't really notice a performance gain and I now have a vibration I can feel in the gas pedal around 2000-3000 rpm. I had a MAC cold air intake on a 99 GT and it worked great. My truck has the edge tuner and straight pipe exhaust (no muffler) so I don't know if one of these is affecting the cold air intake.

NO MUFFLER; if you want better performance get a free flow muffler and if you want loud pipes you can have both.just as the folks at VOLANT,EDGE,and the exhaust people have done the research to make your FORD perform better;it is up to you to take advantage of their research.THE vibration may be coming from the air box installation check for tightness.

I run a AFE stage 2 on my 04 5.4. It has a nice sound and has improved the gas mileage and throttle response

I just installed the Airaid Jr. in my 04. I monitored the IAT with the stock intake, and also with the Jr. kit. I have seen a drop of 5-10 degress vs the stock setup, but this is not the reason that I bought it. I bought it for the free-flowing aspects of the intake tube and filter. And at about 1/3 the price of the other intake systems, it was well worth it since I already had the Edge and 3" exhaust with IMCO hotrod muffler.

Don't see how you can suck in 80 F to 95 F air without a heat exchanger and call it cold air...as the air flow, it picks up heat from friction and radiation from the engine...
All of them should be called performance air intakes, unless they are sucking air through an intercooler...

I think they call it cold air intake just because it's drawing outside air vs. underhood air, even though it's not really cool, as you said.
