Looking for info on INTAKE mods , improvements, replacement gear? whatever is out there would like to know about it. Thanks in advance.

O0ooooo!! Intake is my specialty. AEM cold air intake? Through an intercooler and turbo charger on there which will take care of the air for you. Superchargers do the same thing. Or if your want everything stock but want more power or better fuel efficiency, buy a drop in. All of this can be found doing a simple search on google.com for A4 Jetta intake. I would recommend visiting a custom shop.
