How to increase horsepower in Audi A5?

I recently purchased an Audi A5 and I am looking for ways to increase its horsepower. What are some practical and effective ways to achieve this without compromising the engine's reliability?

Some popular methods to increase horsepower in an Audi A5 include installing a performance air intake and exhaust system, upgrading the engine's software, and adding a cold air induction system. However, it is important to note that these modifications may void your vehicle's warranty.

You can also consider upgrading to a larger turbocharger or supercharger, which will significantly increase your car's horsepower. However, keep in mind that this may also lead to higher maintenance costs.
