How do I increase my Audi A4's horsepower?

I recently purchased an Audi A4 and I'm looking to increase its horsepower. Are there any recommended upgrades or modifications I can make to achieve this?

First, you can start by upgrading the air intake and exhaust system for better airflow. Additionally, investing in a performance chip can improve your engine's power and response.

Another option is to install a new turbocharger or supercharger for a significant boost in horsepower. Just make sure to do your research and choose the right one for your specific Audi A4 model.

If you want to go all out, consider an engine swap for a more powerful engine. However, this can be a more extensive and expensive project, so weigh your options carefully before making a decision.
