Champion Iridium spark plugs offer maximum performance regardless of engine or ignition type. Each plug has an extremely fine-wire iridium center electrode that is "laser-locked" to the center electrode, and a platinum V-trimmed ground electrode to ensure the longest life and greatest erosion resistance.

Features & Benefits:
  • Platinum ground to ensure high performance and long life
  • Maintains stable operating temperature under all engine loads
  • Greatest engine performance regardless of engine type or ignition system
  • Extremely fine-wire iridium center electrode laser-locked to center electrode
  • Exclusive Heat-active Alloy allows electrodes to reach optimal temperature quickly
This spark plug is pre-gapped, but may require minor adjustments with a Spark Plug Gap Tool / Feeler Gauge to match your engine's specifications. For proper engine performance, gaps should be within 0.004" of OE-Recommended value.
