Description

Iridium IX high performance one step colder spark plugs for the Mazdaspeed3 are optimized for better durability, improved center electrode anti-oxidation and anti-erosion, improved ignition, superior anti-fouling and lower required voltage. One Step Colder plugs are only recommended for moderate-heavily modified Mazdaspeed3 MZR motors only.

Note:Iridium IX one step colder spark plugs are not a direct bolt-in for the Mazdaspeed3. These plugs come pre-gapped to .044 and will need to be re-gapped into the .028-.031 stock range. Improper gapping can damage the delicate Iridium tip, so contact your local performance shop if you are unsure how to properly install these spark plugs. We cannot honor and returns or exchanges on damaged spark plugs due to improper gapping or use of the plugs at the improper gap. NGK One Step Colder plugs are only designed for applications with 100hp over stock.
