Ok Im officially confused - Cold Air Intake

[JeffAU1]

Hey all.

As much as I love my AU, I have no idea about it and hence why im confused.

Replacing the air filter myself, well that looks as easy as it can get, but correct me if im wrong. I opened what seems to be the filter box with EEC-V written on the top of it (refer to the pics) and inside was a square filter. So i'll go the Supercheap auto and by a BMC or K&N Filter for my AU and put that new one inside.

But the cold air intake. now thats weird, but then again i have very little knowledge with cars. I have an intake, but the cold air intake i a little wider and therefore will bring more air into the car. I have been reading this webiste as much as i can at home and at work. Here is a link to what im under the impression a cold air intake looks like.

But if u look at this website they charge $249 plus $100 installation.

So what does a "Cold AIr intake" usually consist of ????

And by the way I bought a Rear spoiler off this forum, thanks to all who replied. :voldar02:
