NGK SPARK PLUG D8EA 2120, NG2120

NGK Spark Plug – D8EA

Part No.: 37-D8EA
Key Features:

• Copper Core: The D8EA spark plug utilizes copper to dissipate heat more effectively, cooling the electrode and insulator tip. This helps prevent overheating and improves plug longevity.
• Raised Pre-Ignition Rating: With high-conduction copper and a long nose insulator, the plug enhances heat distribution, reducing the risk of pre-ignition in high-performance engines.
• Non-Resistor: This spark plug does not include a resistor, making it ideal for applications where electrical interference protection is unnecessary.

Specifications:

• Heat Range: 8 – Suitable for engines that operate at slightly higher temperatures but still require good heat dissipation.
• Thread Size: 12mm – Fits a variety of engines with this common thread size.
• Gap: 0.028″ (0.7mm) – Ensures proper spark for ignition.
• Hex Size: 11/16″ (18mm) – Standard size for installation and removal.
• Reach: 19mm (3/4″) – The distance from the tip to the sealing face, ensuring a proper fitment in the engine.
• Terminal Type: Stud Terminal Threads – Designed for use with threaded stud connections in specific engine applications.
• Seal Type: Gasket Seat – Ensures a secure seal during installation.
• Resistor: No – The spark plug does not feature a resistor.
