NGK SPARK PLUG CR7EB 4663

NGK Spark Plug CR7EB

The NGK CR7EB Spark Plug is engineered for optimal performance and longevity. It features a copper wire core for superior heat dissipation compared to iron cores, which enhances overall engine performance. The plug's design efficiently cools the electrode and insulator tip, contributing to stable performance even under high temperatures thanks to its raised pre-ignition rating. Its durable construction ensures a longer lifespan and consistent operation in demanding conditions.

Designed with advanced features to prevent issues, this spark plug offers superior anti-corrosion and anti-seizing properties due to its trivalent metal plating. The corrugated ribs on the insulator effectively prevent flashover, ensuring consistent ignition. A pure alumina silicate ceramic insulator provides exceptional strength and improved heat transfer. Furthermore, the copper core and triple seals work together to prevent leakage, maintaining reliable spark plug performance.

Key Features:

• Wide Heat Range: Copper wire core for enhanced heat dissipation.
• Efficient Cooling: Copper dissipates heat quickly, cooling the electrode and insulator.
