whats the difference between cold air intakes and regular intakes? are cai better for people that have warm environments?

do all intakes improve gas mileage? if not, which do?

also, the previous owner of my cl put a injen sticker on the lower right hand side of trunk. how would i go about taking it off?

 

cold air gives you better top end, short rams are better for low end. as for taking the sticker off, heat it up a bit and slowly peel it off, then use some goo gone to remove the excess residue

 

it all depends on you = )
cold air performs better than short ram and sucks in more dense colder air. . .
i'd sugest you to get the AEM V2 CAI
it doesn't matter if it rains cause it's a very very low chance of even getting water in in ure CAI = )

and about gas mileage. . .hell no it doesn't improve. . or i guess it's just the way i drive = )

 

cai takes the air from below the car where its cooler (outside engine bay + cold air is denser - sits closer to the ground)
