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.

 

Irridiums will get you roughly 5000-8000kms out of a good set, if you want increased durability try our Ruthenium Plugs you'll get 8000-12,000kms!

 

We can gap the plugs for you, please select your options, if you're unsure, we usually go with a safe 0.64mm
