Help! Need to know what induction kit / air filter for M3

[jaydub]

Hi all

Can anyone give me some advice, I want to get a air induction kit / Air filter. What is the best one i can get for sound and performance? Can i fit a CSL one? or is it better and cheaper to look at offers?
I have an 2005 M3 SMG 2.

Cheer all.
