Wow, I'm really new to the Audi world. Just got a 2005 A4 Cabrio 1.8T. So here's 2 newb questions:

1. I'm assuming my car is a B6 based on this forum, but it looks like there was a update in 2005.5. How can I tell which I have? Sounds horrible I know.

2. I would like to give it more power. Where do I start? I'm thinking K&N air filter first. Beyond that, what should I do? Looks like cold air intakes aren't effective on the 1.8T. Appreciate any direction.

While I'm at it, what other upgrades should I consider?

Thanks!
