How to Increase the Horsepower of my Audi 80?

I am looking for ways to boost the horsepower of my Audi 80. What are some modifications or upgrades that can improve its performance?

One way to increase horsepower is by installing a cold air intake system. It allows for cooler and denser air to enter the engine, resulting in improved combustion and more power.

Another option is to upgrade the exhaust system. A larger diameter exhaust and performance headers can improve exhaust flow and unleash more power.

Tuning the engine and remapping the ECU can also increase horsepower, but it is recommended to have it done by a professional to avoid any potential engine damage.
