$450 christ they are criminals to sell it at that price.
Even the best home made "semi-professional" CAI would not cost a hundred bucks, and it would work a heap better.
Temp at the CAI intake is mostly lost as air travels along the hot air box, and the very hot black corrugated intake hose where most possible advantages of cool air is lost, the only advantage is the volume of air pushed in rather than sucked in, being semi ram flow.
The only way to have genuine CAI requires complicated bonnet / sealed pod type, or to insulate the large black hose with both asbestos wrap and aluminium foil, and a insulated heat deflector between the inlet and headers.
Having the headers so close to the inlet defeats any definitive true cold air HP, like on rainy days where the air is heavy where all vehicles have more grunt.
Similar to by theory but opposite to altitude tuning where the air is very thin reducing HP.
The asbestos wrap covered by aluminium foil with a deflector would give a noticeable HP increase and costs a heap less that $450.
Anyone interested in having the gear for turbo engines, extractor / manifold wrap and all the gear needed, check this place out.
