Getting power out of a 63 /6?

I did not mean to indicate that the overpriced "cold air intake" systems. I was simply pointing out the idea behind them. As 805moparkid the colder denser air can help increase hp and mpg some. But as pointed out more air needs to get out also so a large exhaust. I am getting ready to do the exhaust on mine and I like the idea of 2.5 inch.

My idea at least in my case is bringing the intake out through the radiator walls. I think it would be out of the way and a flexible hose like a dryer hose would work well.
