Default Intercooler applications for NA cars

This is probably a really stupid question, but for anyone who would know, since such a person is not me, is it at all possible for an intercooler to serve as an air cooler for a NA car as part of an intake setup? I was thinking, if it is possible, I am sure there could be some pretty creative setups with a used WRX intercooler on a GC8 throttle body.

Too much restriction
Surrounding air is HOTTER than what flows through the intake

Realize the point for intercooling a turbo car is that the air increases temperature as the pressure increases. Your current NA intact tract is actually a VACUUM so it should be ever so slightly cooler.

You would be better off insulating the entire intake, both from the engine (huge source of heat) using phenolic spacers and from the ambient air in the engine bay.

Yea, the air you're planning to cool is already at outside ambient temperature (if you have a CAI). The intercooler, at best will only cool the air at ambient temperature, but it probably won't hit that, with the warm air inside the engine bay. So IC's for NA applications are pretty much useless.

What about a heat sinc structure around the intake and intake manifold? Pretty much, no change to the inner working, just some fins on the outside to increase surface area and cooling.

Kinda somehting I've been day dreaming about...you know, to make the hood scoop functional.

hehe, strap on old cpu heat sinks w/ fans on top of the intake manifold runners

anyway, you'd have to duct the air from the scoop towards the intake manifold rather than it flowing directly towards the firewall

I was thinking more along the lines of heatsinc fins on the manifold or intake tubing, to take advantage of our scoops and vents.

yea, but you gotta get the cold air flowing towards the front of the engine bay, rather than it going straight towards the firewall, so the cool air can hit your heat sinks on the manifold

Yeah, that is the general idea, functional hoodsoop as part of some sort of intake.

Heat sinks are still going to WARM the air, the air in the intake is taken from outside but is under a negative pressure, its colder that any other air in the vicinity of the vehicle.

The air within the intake then absorbs heat that is coming from the heads. The first step is a heat barrier between the heads and the intake.
