How can I improve the engine performance of my Audi 80?

My Audi 80 seems to be running a bit slow lately. Is there anything I can do to increase its engine performance?

Steve, have you checked your air filter? A clogged air filter can greatly impact your engine's performance. Consider replacing it.

Hi Steve, another thing to consider is your spark plugs. These should be replaced regularly to ensure optimal performance. You may also want to check your spark plug wires for any wear and tear.

Hi Steve, have you tried using a high-quality fuel additive? This can help clean out any buildup in your engine and improve its overall performance. Also, make sure you are using the correct octane level for your vehicle.
