NGK SPARK PLUG D9EA 2420

NGK Spark Plug – D9EA

Part No.: 37-D9EA
Key Features:

• Copper Core: The D9EA spark plug utilizes copper wire to dissipate heat more efficiently, which helps cool the electrode and insulator tip quickly, preventing overheating and enhancing the plug’s longevity.
• High-Performance Engine Compatibility: With a raised pre-ignition rating and high-conduction copper, this spark plug is built to handle the heat demands of high-performance engines.
• Non-Resistor Type: The D9EA is designed without a resistor, making it suitable for engines where electrical interference protection is not required.

Specifications:

• Heat Range: 9 (ideal for engines operating under higher temperatures).
• Thread Size: 12mm (standard for various motorcycles and small engine applications).
• Gap: 0.028″ (0.7mm), providing the optimal spark for ignition.
• Hex Size: 11/16″ (18mm), a standard size for easy installation and removal.
• Reach: 19mm (3/4″), ensuring proper depth for secure installation.
• Terminal Type: Stud Terminal Threads, designed for threaded stud connections.
• Seal Type: Gasket Seat, ensuring a tight and secure seal.
• Resistor: No (this plug does not have a resistor, making it suitable for certain applications that don’t need it).
