howdy all

My name is Rads and I am new to this so please be gentle and excuse my lack of knowledge.

I currently have a stock 2005 VW Golf and wanted to do make minor modifications to it. I've got a bout $400 to spend so nothing major. I want to play around with the air filter/air box and I have read so much conflicting stuff on the net its actually frustrating.

What I would like to know is;

1) For my stock VW Golf would a CAI or SRI be best?
or
2) The pipes/tubes from a SRI kit modified to fit the stock airbox with a replacement drop in filter?

In terms of running rich or lean, does a CAI or SRI play a part in that?

Sorry if I am pushing my luck with my questions but i would really appreciate the advice.

Thanks in advance
Rads
