they will both give you about 5-10 depending on which brand but i would go with a short ram intake from Weapon-R, it recently won in a Test against all the 'best' brands in the industry.. I would go with the short ram for sure.. the cold air intake can actually do a thing called hydro-lock, it's when water gets inside the air filter and goes down in the engine which you can imagine isn't good.. And don't think i know anything about intakes.. or integras for that matter
