Newbie Question.

Hi, I am investigating the whole induction kit thing. From what I can see, Cold Air Induction and "normal" induction kits are very different. I have been reading about the PRM kit. Is this just an air induction kit, not a cold induction? Also, I see some people have just bolted on like a K&N filter. Is this a noise-only cheaper route? I would like something with very little installation, good noise and no drop in BHP....what should I be looking at?

I like the look of the PRM one...how much cash would this set me back?

Thanks as always,

Adrian
