I have an A4 b7, 2.0t quattro.
All stock. Mainly for my commute and some weekends.

I am looking into the APR carbonio cold air intake.
to open it up a bit, i know i wont get much gains but atleast something.

My question is if the intake is good on a stock car?
the apr site says "Works on APR Stage III Cars with Larger MAF"
does that mean I need a stage III or is it just compat.?

thanks!
