I wouldn't do much of anything. The reason the intercooler works on the MCS is that the compressed air that comes out of the supercharger is *much* hotter than the outside air. This means that the outside air flowing over/through the intercooler will cool off the hotter compressed air inside the intercooler. The heat transfer only occurs because of the temperature difference.

In a naturally-aspirated engine, the air flowing through the intake tract won't be much hotter than the outside air. Without the temperature difference, there's no (or very little) heat transfer from the intake air to the outside air.

No, the intercooler wouldn't do anything. If the air inside the intercooler and the outside air are close to the same temperature, then there's no significant heat transfer, and the intercooler is basically just a pipe.

An intercooler only works if the air passing through the inside of it is a lot hotter than the air flowing around the outside of it. This is true in a supercharged or turbocharged engine, but not in a naturally-aspirated one.

An intercooler would have a detrimental effect. Flow would be interrupted/slowed by the impeding core fins. On a NA motor smooth transitions in the flow path are more crucial than for FI with only atmospheric pressure to move air into the head.

If you want cool air, duct in some air off your AC into your intake chamber.

For the MC, better than any intercooler alone would be a turbo kit.

Alternatively, if you have already done the easy upgrades like:
Intake
Cat-back exhaust
plug wires
ECU tuning
Larger throttle body

Then next upgrades for power would be:
Ported and polished cylinder heads
Race Camshaft
Header with race catalytic converter

Other upgrades:
Quaife differential
Light weight rims and wider sticky tires
