Make sure you get an intake that routes the air from the outside. In other words, is your intake filter sitting inside the engine compartment? If it is, this is more of a "hot air intake" as it pulls in hot air from the engine compartment, at which point you're actually losing horsepower. The stock air filter assembly have the tubes getting the air from the fender or from the front, in both cases getting cold air from the outside. Cold air is more dense, allowing for better combustion and thus increasing power. Granted, its not that much power to be gained this way on a naturally aspirated engine (forced induction is a totally different story though.) So just make sure you get one where the filter sits outside (gets its air from the outside) somehwere, otherwise you're wasting your money.
