Cold Air Intake HP Debate - Is it worth it ?

At 120 hp/ liter the z needs to make around 450 hp. Yes the s2k makes no tq and yes it is tiresome to have to rev it to go anywhere. I can't think of 1 nissan the hit 100 hp/ liter.

I don't think anyone wants to take the time to do this. Our cars are already well designed in the intake dept but like someone else said here, it all comes down to personal preference. "I" believe that colder air going In has to have a slight advantage in the overall HP/tq gain dept but that's just me....
