Hey, just a newbie question, but really important that I ask, as i'm not a mechanically minded person,

Just wanting to put an air intake into my car (apexi or K&N) etc

Currently have an MY02 WRX, with a 3inch full exhaust turbo back,

Need to know

a) Cheapest place in perth to get an air intake
b) Preferably somewhere that can help me install it, or at least they supply a kit so its really easy to do, expecially because i have that air electronic gauge on the pipe comming out,
c) Which is the best recommended air intake for my general purpose use?

Thanks in advance members! (Near Perth/ north/west area)
