    it won't matter, any cold air will help, doesn't matter what it will go thorugh.
    The cold air helps because colder air is denser than hot air. However i think that if it gets too cold the fuel doesn't atomize well or somthing wich can acutally degrade performance

    well cold fuel is also ok if you have a hot manifold... but I removed the manifold heater so I need the warmer fuel.

    cold air = more dense = more bang in the same space (cylinder/combustion chamber)

    each 10 degrees decrease is about 1hp. in some cases cold air intakes are 60-80 degrees cooler than the air in the engine bay=6-8hp
