Every 2 years or 30k miles in a newer bike. My older 2007 service manual says 20k miles. Its about the cheapest thing there is on a Harley so why not

Man I just don’t get peoples cheapness. Local Wal-Mart has the Autolite equivalent 4164 for $1.98ea- why on Earth would you put an old plug in when they both can be changed for under $5?
