Detailed Description

NGK’s Standard Spark Plug line is built around the company’s long history as an OE supplier for domestic and import vehicles in North America. The 2910 spark plug follows that approach with a copper core center electrode, nickel electrode materials, and a standard ground configuration that supports stable combustion in everyday driving conditions. The AB-6 reference and NGK 2910 part number help simplify cross-checking during maintenance and catalog lookup.

This spark plug is suited for drivers and technicians servicing vehicles that specify a flat-seat, 18 mm plug with a .429 reach and .028 pre-gap. It is a direct fit style service part for many ignition tune-up jobs on Honda Civic and Toyota Corolla applications where the engine calls for a conventional resistor spark plug.

This part cross-references Autolite 386 and Champion Spark Plug 502 for the same application.

What It Helps Address

• Hard starting caused by worn or fouled spark plugs
• Rough idle from inconsistent spark delivery
• Misfire conditions related to aged ignition components
• Reduced fuel economy from inefficient combustion
• Loss of throttle response during routine maintenance intervals

Installation Notes and Tips

Verify the engine’s required thread diameter, reach, seat type, and heat range before installation. Confirm the plug gap against the vehicle service specification, even though this plug is pre-gapped at .028. Use the correct socket size and torque to avoid damage to the threads, insulator, or cylinder head. Check the ignition system, coil condition, and plug wires or boots during service to help prevent repeat misfire concerns.
