How do I increase horsepower in my Audi A3?

I have a stock Audi A3 but I want to add more power. What are some modifications I can make to increase horsepower?

You can start by upgrading your air intake system and exhaust system. This will provide better airflow, resulting in a slight increase in horsepower.

Another option is to install a performance chip or tuner. This will optimize your engine's performance and potentially add significant horsepower.

Consider adding forced induction, such as a turbocharger or supercharger, to really boost your horsepower. Just make sure your engine can handle the extra power.
