    Why not intercool NA engine?

    Wouldn't it improve the performance or would the cooler be restrictive and add weight that would make this not useful?

    Massive restriction of air flow. Without a forced induction device to provide pressure to move the air through the ic it would not be a good idea.

      Not enough heat in the non-FI intake charge to need an intercooler.

        Run the A/C lines through the throttle body.

          Only the High pressure post compressor line. The heat in the low lik=ne would negate the cooling. Maybe Direct Exhaust Injection?

              Cool the ambient outside air with ambient outside air?

              I'm confused.

                I just wrap one of those freezer injury bags around my air intake. Cheap 20hp right there.

                  The only reason to intercool a FI engine is because the process of compressing the air generates a lot of heat and raises IAT, so you need the intercooler to bring the air back down to ambient temp.

                  NA engines breathe ambient air, making an intercooler absolutley useless.

                          good idea. just make sure you remember to take it out once you are done driving to put back in the freezer.
