How much does an intercooler increase gas mileage?

How much does an intercooler increase gas mileage?
It doesn't. An intercooler cools and densifies the air entering the engine after being compressed (and therefore heated) by a supercharger or turbocharger. Because the air entering the engine is denser (more molecules), it needs MORE gas in order to maintain the correct air-to-fuel ratio. An intercooler is intended to increase horsepower, which means increased gas consumption... not decreased.
