so in the end i got a 2003.5 black p5! MT of course...altho i'm still learning. :P it's great! i think i'll have a lot of fun in that car. got a good deal and awesome service. if this car lasts me, i'll be hooked on mazda.
thanks for all of you who answered all those questions of mine from the past. i'll have more questions in the future, but now it'll be about boosting it up.
which btw just to avoid making an unnecessary 2nd post, i'll ask, people put I/H/E to refer to intake, header, and exhaust right? i've seen some way intake header as if it's one thing. which is it? also are they basically the same thing as CAI? i've tried searching but i can't seem to find exactly what i want to know (i found exp. for CAI). i think the first thing i'd do to quicken up the car is one of those...
anyway, thanks in advance.

Yeah, I/H/E refers to intake/header/exhaust.

A CAI is short for cold air induction, meaning the intake filter is located outside of your engine bay so it draws cooler air. Intakes come in a variety of flavors, but most are short-ram (pretty short length of tubing with filter that draws air from engine bay) and CAI.

Opinions are split on whether or not CAI's actually do any more than a short-ram or standard intake. It's up to you.
