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.
