NGK 7317 R5724-8 V-Power Racing Spark Plug

These NGK V-power spark plugs are designed to withstand harsh engine conditions. They feature a unique v-cut in the center electrode. This design directs the spark to the edge of the electrode which aids in faster spark development, increased ignitability and reducing quenching. 

• Special insulator nose configurations improves throttle response
• Corrugated ribs prevents flashover
• Pure alumina silicate ceramic insulator provides better heat transfer and provides superior strength
• Trivalent metal plating provides anti-corrosion and anti-seizing properties
• Copper core aids in heat removal
• Triple seals prevents leakage
• V-Groove increases ignitability
