KN 57i induction for astra 2.2?

[DCP]

Has anyone tried this induction kit on an astra sri 2.2 2003?? I was also wondering what the damage might be?? Should i go to my local autoban (melbourne) and maybe hassle them. Would it be easy to install myself??....and if i ask another question im going to bloody pop:eek: ...sorry... cheers.

........sorry..also am i better off not going the 57i and doing the air box mod, throwing in a K&N panel filter and getting the c pipe from a vectra 2.2 instead. I have been told that the 57i will not benifit my car and even reduce bhp. (ahh what to believe...eh). Dazed and confused.
