NGK G-Power® platinum spark plugs feature a single platinum tip, 98% pure copper core and a .6 mm fine-wire center electrode for more focused sparks and better ignitability.

Features & Benefits:
  • Trapezoidal ground electrode allows for higher ignitability and reduces quenching
  • High-grade alumina silicate ceramic for stronger insulation to reduce dielectric punch-through (caused by spark exiting through side of ceramic)
  • Trivalent plating means no anti-seize required
  • Cold-rolled threads prevent cross-threading and damage to cylinder heads
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.
