NGK 7764 Spark Plug
NGK Laser Iridium Spark Plug 7764
NGK 7764 is a Laser Iridium High Ignitability spark plug built for precise ignition performance and OE-style durability. It uses an iridium center electrode tip, a square platinum ground electrode tip, and a 0.036 pre-gap to support consistent spark delivery in modern ignition systems.
Compatible With Honda Civic and other applications that call for NGK 7764, this spark plug reflects NGK’s long OE supply background and North American manufacturing focus. The 10 heat range, 10.00 mm thread diameter, 26.5 reach, and flat seat help match the original service requirements for the correct engine application.
Key Features
- Laser Iridium High Ignitability design for stable ignition performance
- Iridium center electrode tip material for long service life
- Square platinum ground electrode tip design for efficient spark exposure
- 0.036 pre-gap for OE-style setup
- 5000 ohm resistance for ignition system compatibility
- Flat seat, 10.00 mm thread diameter, 26.5 reach, and 14 mm hex size
- Non-removable nut terminal for standard ignition connection
Product Details
NGK 7764 is a spark plug engineered for vehicles that require a fine-wire iridium center electrode and a high-ignitability ground design. The copper core center electrode supports heat transfer, while the nickel ground electrode core and standard ground configuration help maintain reliable operation under normal service conditions. This part cross-references BBB Industries 7764 for the same application.
Common Issues This Part Can Help Address
- Hard starting caused by worn spark plug electrodes
- Rough idle from inconsistent spark delivery
- Misfire conditions related to plug wear or gap growth
- Reduced throttle response from weak ignition performance
- Service intervals overdue on OE-style ignition maintenance
Installation Notes
Verify the engine’s required thread diameter, reach, seat type, heat range, and terminal style before installation. Check the gap against the vehicle specification before use, and confirm the application against the original part number 7764 or interchange reference 31910-MEN-A31. For Honda Civic service, match the plug to the exact engine and model year listed by the vehicle manufacturer.
