NGK Racing R2525-10 Spark Plug

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. Tested to the highest original equipment standards, these plugs are crucial for vehicle maintenance.

• High grade alumina silicate ceramic
• 98% pure copper core enables the spark plug to quickly dissipate heat
• Cold-rolled threads prevent cross-threading and damage to cylinder heads
• Trivalent plating eliminates need for anti-seize
• Designed to reduce the quenching effect resulting in better ignition performance
• Gap measurement with laser precision throughout production process
