How do I improve my Audi 80's overall performance?

I've been experiencing some issues with my Audi 80's performance lately, and was wondering if there are any specific steps I can take to improve it. Specifically, I'm looking to address issues with fuel efficiency and power. Can you provide any tips or advice?

Improving your Audi 80's performance essentially involves optimizing its engine and drivetrain systems. Some steps you can take include regularly checking and replacing air filters, spark plugs, and fuel injectors. You could also consider getting an engine tune-up and using higher octane fuel. Additionally, make sure your tires are properly inflated and aligned. By following these guidelines, you should see a noticeable improvement in your car's performance.

Aside from making sure your car is well-maintained, you could also consider installing aftermarket performance parts such as air intakes and exhaust systems. These can greatly improve your car's power and fuel efficiency. However, keep in mind that these modifications may void your car's warranty. Make sure to do thorough research before making any changes to your vehicle.
