What is the purpose of the spark plugs in an Audi 80?

I am curious about the specific function of spark plugs in an Audi 80. How do they contribute to the functioning of the car and what role do they play in the engine?

Spark plugs play an important role in the ignition process of the engine. They create a small spark that ignites the fuel and air mixture in the engine, allowing it to start and run smoothly.

In addition to starting the engine, spark plugs also help to maintain its efficiency and performance. Bad or worn out spark plugs can cause a decrease in fuel economy and power.
