ZFR6F-11 V-Power Spark Plug – Single Fine-Wire Unit (Part #4291)

Description

• V-groove center electrode improves ignitability and reduces quenching
• 98% pure copper core increases heat dissipation for reliable starts and prevents spark plug from overheating
• High-grade alumina silicate ceramic insulator for superior strength and heat transfer
• Cold-rolled threads to prevent cross-threading and damage to cylinder heads; Trivalent plating eliminates need for anti-seize
• Quantity: 1 per package

NGK nickel spark plugs feature a specially designed v-groove center electrode, improving ignitability and reducing quenching. The 98% pure copper core delivers increased heat dissipation for more reliable starts and reduced risk of overheating. Cold-rolled threads prevent cross-threading and damage to cylinder heads. Trivalent plating eliminates need for anti-seize. High-grade alumina silicate ceramic insulator.
