Hey everyone I've got a 2002 Audi A4 1.8t
I have already done a few mods and know of some that I am going to do but I am looking for some more opinions.
So far I have an APR intercooler, afe cold air intake, a full magnaflow exhaust. and a GIAC k04 w/o software.

later this month I am also going to get stage 2+ apr ecu with apr fuel injectors.

so basically what I am asking is what else is there to do.

also I was wondering if (much later on) an s4 engine could fit in the a4 b6 bay.

and of course I am looking to make the car look better too, any ideas of what body kits look good open to any suggestions.

Thank you
