How to increase the engine performance of a Audi 80?

I am a proud owner of an Audi 80 and I am looking for ways to increase its engine performance. What modifications should I consider and what are the potential benefits? As a car enthusiast, I am open to both simple and advanced engine upgrades. Your advice would be greatly appreciated.

First, consider upgrading your air intake system to a high-flow air filter. This will allow more air to flow into the engine, increasing its performance.

You can also install a performance chip to optimize your Audi's engine programming, resulting in higher horsepower and torque.
