I'm considering possibly putting in a cold air intake into my 2000 ZX2, but the question I have is 1.) would a short ram air intake be better and 2.) is it worth it? and 3). does it hurt the engine, car at all?

Also I may put headers in as well, but same question stands, that being 1.) Worth it? and 2.) Hurt the car?

if its hurt the car or wasnt worth it...no one would do it. Sort ram doesnwork on a car that has very little airflow up to the air filter, a CAI is always best.
