I'm sure that with a thermometer and a scientific analysis it may be sucking in some warmer air, etc but the real test for me was real world experience and all I can say is it is night an day with the stock airbox.
Couldn't be happier with it.

its because you just spent $200+ and your brain is trying to cope with money wasted by telling your self "there is a gain... there is a gain..." its a placebo effect. its like 200hp civic si feels different perhaps slower/lagging than 200hp gti because its not boosted, but in the end its still 200hp.
