NGK Iridium IX Spark Plug — BR9ECSIX-5

Iridium IX spark plug from NGK — the firing tip wears slower than nickel or copper plugs, so the gap stays right and the bike keeps starting clean for the life of the maintenance interval.

• 0.6mm iridium center electrode tip welded to a copper core for fast heat transfer and clean firing under load.
• Trivalent-metal plating on the threads to resist seizing and corrosion in the head over the life of the plug.
• Spec-correct heat range and reach for the bikes it's listed for — same dimensions as the OEM standard plug it replaces.
• Gap is preset at the factory to NGK's reference; check it against your service manual before fitting.
• Direct replacement: no jetting or wiring change. Torque to spec, run.
