NGK Iridium IX Spark Plug — CR8EIA-10

OE-fitment iridium plug used by major motorcycle and ATV manufacturers — laser-welded platinum disc on the ground electrode plus an iridium center tip for the longest service life NGK builds.

• Iridium center electrode plus a laser-welded platinum pad on the ground electrode — both rare metals erode much slower than nickel, so the gap stays stable for the full service interval.
• Fine-wire center electrode (typically 0.6mm) needs less voltage to fire and ignites the mixture more reliably at idle and on a cold start.
• Specified as original equipment on many late-model fuel-injected motorcycles, ATVs and personal watercraft — direct replacement, no gap or heat-range change.
• Trivalent plating on the metal shell resists corrosion in salt air and prevents thread seizure in aluminum heads.
• Sold individually — match the part number on the plug body to the OE call-out in your owner's manual.
