How can I increase the horsepower of my Audi A6 engine?

I've been wanting to add more power to my Audi A6 engine but I don't know where to start. Any suggestions on what modifications I can make to increase horsepower without sacrificing reliability?

Adding a cold air intake and a performance exhaust can significantly increase your A6's horsepower. However, make sure to do your research and choose reputable brands to avoid any potential issues with your engine.

Another option is to install a performance chip, also known as a 'tune,' which can optimize your engine's performance and give you a noticeable increase in power. Just be wary of cheap or generic chips as they can do more harm than good.
