Mazda Miata Spark Plug

Your Mazda Miata provides the thrilling driving experience of a convertible roadster, but with a reasonable price tag. AutoZone offers Miata performance spark plugs at low prices to make it easy for you to keep your car zipping along. Our selection meets factory specifications to ensure the best engine efficiency.

A quality Mazda Miata spark plug is able to withstand the extremely high temperatures found inside a cylinder. Spark plugs come in different temperature heat ranges with variations in the size of the contact area. The voltage is isolated at the electrode by ceramic inserts, and when it jumps the gap, it's conducted to the engine block, where it's grounded. Come by your local AutoZone store to get spark plugs for Mazda Miata, and benefit from free engine diagnostic testing and free battery testing during your visit.
