The air filter and oil filter often need attention at the same service on the Mazda MX5 NC (2005 - 2015), although they work in different places. The air filter keeps dust out of the intake air, while the oil filter traps particles in the circulating engine oil. Alongside suitable engine oil, a clean oil filter helps maintain lubrication. With the air filter, the type of element determines whether it should be replaced or cleaned as specified.
