Hey stupid question but does HKS stand for hotshot intakes or is HKS it's own brand name? Also if I get a CAI with a cone filter will the car sound any louder? I'm not much on noise, I like quiet rides. One more thing, If I get a CAI and cone filter will I be able to tell the difference in power from my stock 6 and I heard if you get metal or aluminum intake pipes then they get hot and ends up heating the air it takes in....fact or fiction? Sorry for all the questions but I'm pretty young and there's alot that I don't know.
