NGK SPARK PLUG D7EA 7912

NGK Spark Plug - D7EA

Part No.: 37-D7EA

Key Features:

• Copper Core: The D7EA spark plug uses copper wire for efficient heat dissipation, keeping the electrode and insulator tip cool and ensuring optimal performance under high-temperature conditions.


• Raised Pre-Ignition Rating: High-conduction copper and a long nose insulator help improve heat distribution and reduce the risk of pre-ignition in high-performance engines.


• Non-Resistor: This spark plug is designed without a resistor, making it suitable for engines that do not require electrical interference protection.

Specifications:

• Heat Range: 7 - Suitable for engines that operate at high temperatures but require a spark plug that can handle and dissipate heat efficiently.


• Thread Size: 12mm - Standard size for many small engines, including motorcycles and ATVs.


• 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 proper fitment.


• Terminal Type: Stud Terminal Threads - Designed for use in engines that require threaded stud connections.


• Seal Type: Gasket Seat - Ensures proper sealing during installation.


• Resistor: No - Does not include a resistor, ideal for applications that do not need electrical interference protection.
