The first spark plug change is at 7,500 miles so might as well change the filter too. It is a PITA to do. Here is my filter and spark plugs at 8,500 mile change.

JMHO, but, those plugs are designed for at least 50,000 miles. Why waste $ and time changing them.

The service guide recommended changing the spark plugs at 7,500 miles.
