WIX has developed optimum particle size retention quality in filter media through extensive engine wear tests in the real world, at the race track and in the lab. We use WIX oil filters on our own Miatas and all the Miatas in our service department.

WIX OEM-style replacement fuel filters for the Miata MX5. Fuel filters are too often overlooked. Mazda recommends replacing your Miata fuel filter no later than every 5 years or 60k miles.

Air filters are too often overlooked. Mazda recommends checking your Miata's air filter once a year or every 15K miles and replace as needed. If you live in a dusty environment check your Miata's air filter regularly and replace it if it's clogged.
