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.

    Used these as replacements for OEM on my 2008 Speed3 and they work great. Appear to be excellent quality and the car runs very well.

    My spark plugs arrived quickly and exactly as expected. Gapping and installing them went smoothly as well. I don't have anymore blowout since putting them in.
