Hot Air Intake - how hot is too hot

[talljerry]

I see no point for a Hot Air Intake, just use a block heater when its cold outside.

The point of a hot air intake is to raise the intake air temperature. Warmer air is less dense, and therefore requires less fuel to burn at the proper air/fuel ratio. Plus, not everyone has the ability to use a block heater. For example, I park my car out on the street. I can't be draping extension cords over the sidewalks on a nightly basis.
