How often should I replace the spark plugs in my Audi A1?

I have heard varying answers about when to replace the spark plugs in my Audi A1. Some say every 30,000 miles, while others say every 60,000 miles. What is the best practice for my specific car model and driving habits?

As a general rule, Audi recommends replacing spark plugs every 45,000 miles or 3 years, whichever comes first. However, this can vary depending on your specific driving habits and the condition of your spark plugs. It's always a good idea to consult with a trusted mechanic for personalized advice.

In my experience, it's better to err on the side of caution and replace spark plugs every 30,000 miles. This will help ensure optimal performance and fuel efficiency for your Audi A1.

I have found that with regular maintenance and proper care, spark plugs can last up to 60,000 miles. However, if you notice any symptoms of worn spark plugs, such as difficulty starting the car or decreased fuel efficiency, it's best to have them replaced earlier.
