Spark Plugs Change

The iridium tipped original OEM spark plugs in a Miata with the SkyActiv-G 2.0 PE-VPS 2.0 liter inline four cylinder engine should be replaced every 75,000 miles. They should also be checked before that mileage to see their current condition.

Oil Change & Filter

Rear Brake Pads Change

The rear back brake pads of a Miata tend to last twice as long as the front pads or anywhere from 60,000 to over 100,000 miles. (Or a lot less if you autocross or drag race your car.)
