And my comments on your hot air intake were exactly what they look like on the surface, no hidden digs. Hot air is less dense which hurts power and acceleration, less restrictive intake might help, it's not clear where the balance would be. But if you're getting more power, then that shows where the balance is in your truck.
If the air flow increase is enough, it offsets the negative effects of the warmer air that makes it less dense. For example, say the increased air flow without the negative effects of it being warm air adds 10 hp, but the air being warmer takes off 4 hp, you still have a gain of 6 hp over the stock cold air box.
If the stock cold air box could flow as much as the ram air, then that would give you the full 10 hp increase.
