I had an Idea with the K&N intake..

We all know about the K&N 77 series by now...
I think the 63 is looking better now,.

But I had this idea. the K&N 77 has a metal air intake tube.
Now, most of the forum agreed that this would effectively heat up the air, and therfor decrease air density and horsepower.
BUT! What if you welded/soldered/thermal expoxied a Heatpipe or copper strip (any computer guys out there?) from your airconditioning cold line?

The A/C line is quite exposed, and gets quite cold when the A/C is on. The heat from the Metal K&N pipe would flow along that copper (or heatpipe) metal to the A/C line, and be cooled down very quickly. This would in effect make the metal intake line on the K&N COLD. Now, in typical use, this wouldnt matter that much, however, I always turn off my A/C before I race someone off the line. SO now I have a cold Intake (courtesy the A/C) and no additional engine load!
In the summer, it would decrease my cooling of the cab a little bit, but I can take the heat...

and then you insulate the intake tube, and it will stay cooler...

I saw a truck in a magazine (Car Craft, Hot Rod, etc) years ago that was set up like this. I think it was one of the Cyclone/Typhoon turbocharged trucks.

The guy had installed a little evaporator coil in the intake tract and had piped it into the truck's A/C system with some Y-blocks and hard tubing. Makes for a really cool (

pun intended

) intercooler.

Only downside I can see is that to get any intake cooling you must have the A/C compressor switched on. On a naturally aspirated vehicle any gains from the cooling would probably be negated by the extra load from the compressor.
