V-Power; Pre-Set Gap: 0.032"
V-Power Spark Plugs are named for their specially designed v-groove center electrode to improve ignitability. Tested to the highest original equipment standards, these plugs are crucial for vehicle maintenance.

Features & Benefits:
  • Cold-rolled threads prevent cross-threading and damage to cylinder heads
  • Trivalent Metal Plating has superior anti-corrosion and anti-seizing properties (eliminates need for anti-seize)
  • High-grade alumina silicate ceramic creates a stronger insulator to reduce dielectric punch-through (caused by spark exiting through side of ceramic)
  • 98% pure copper core increases heat dissipation for reliable starts and prevents spark plug overheating
  • 90 degree V-Groove center electrode allows the spark to occur closer to the outside of both the center and ground electrodes for better flame expansion, reducing quenching and improving ignitability
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.
