Spark Plug - NGK DR7EA

NGK nickel spark plugs feature a specially designed v-groove centre 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
