How do I increase the horsepower of my Audi 80?

I have a 1990 Audi 80 and I want to boost its power. What are some upgrades I can do to increase its horsepower?

First, you can start by upgrading the air intake system. A cold air intake will provide more oxygen to your engine, resulting in increased horsepower.

Another option is to install a performance chip, which can optimize fuel and air ratios and give you more power.

You can also consider upgrading your exhaust system to a high-flow one, which will help your engine breathe better and improve performance.
