NGK Iridium IX spark plugs are a high quality performance spark plug featuring an iridium tip for very consistent and stable spark. Iridium also has a very high melting point which keeps it functional in a high heat, high performance engine. The Iridium IX spark plug also features special plating to resist corrosion and seizing.
Commonly used in the Mazdaspeed 3, Mazdaspeed 6, Mazda CX-7 and other engines. This is a one step colder plug (higher heat range) when using on the MZR DISI engine.
