How often should spark plugs be changed in an Audi R8?

I have recently purchased an Audi R8 and was wondering how often the spark plugs should be changed? I've heard conflicting information and want to make sure I am maintaining my car properly.

According to Audi's official maintenance schedule, the spark plugs should be replaced every 35,000 miles or every 3 years, whichever comes first.

With the high performance engine of the Audi R8, it is recommended to change the spark plugs every 20,000 miles to ensure optimal performance.

As a mechanic who specializes in Audi vehicles, I recommend changing the spark plugs every 30,000 miles to avoid potential misfires and maintain the engine's smooth operation.
