The NGK Spark Plugs R5670-5 racing spark plug is designed to deliver reliable ignition performance for demanding high-performance applications. This spark plug uses a pure alumina silicate ceramic insulator that provides excellent strength, effective heat transfer, and dependable operation under elevated engine temperatures. Its racing-oriented construction supports consistent combustion and performance where durability and thermal control are essential.
Trivalent metal plating helps provide superior resistance to corrosion and seizing, supporting easier service and improved long-term reliability. Triple seals help prevent leakage, while corrugated insulator ribs reduce the risk of flashover for dependable ignition performance. A copper core assists with heat removal, helping the plug manage operating temperatures across suitable racing and performance engine applications.
