NGK 92222 Spark Plug
NGK Standard Spark Plug 92222 Overview
NGK Standard Spark Plug 92222 is a direct ignition service part built around NGK’s long-standing OE manufacturing background. It uses a copper center electrode, nickel center electrode tip, and nickel ground electrode components to support stable spark delivery in everyday driving conditions.
For drivers searching for an NGK spark plug for Honda Civic, Toyota Corolla, or similar import and domestic applications, part number 92222 offers a standard-design replacement with a 0.032 pre-gap, 5,000 ohm resistance, and a flat seat configuration.
Key Features
- NGK Standard Spark Plug line for routine ignition service
- Part number 92222 / LMAR9G
- Copper center electrode core for consistent conductivity
- Nickel center and ground electrode tip materials
- Standard ground electrode design with one ground electrode
- 5,000 ohm resistance for ignition system noise suppression
- 0.032 pre-gap size
- 10 mm thread diameter, 14 mm hex size, flat seat
Product Details
NGK has supplied original equipment spark plugs for a wide range of domestic and import vehicles in North America, and this Standard Spark Plug follows that OE-focused approach. The LMAR9G design is intended for engines that call for a 10 mm thread, 26.5 reach, 49.00 insulator height, and heat range 9. If you are replacing worn plugs in a Honda Civic, Toyota Corolla, or another vehicle that specifies this configuration, 92222 provides a straightforward service replacement.
This part cross-references Dorman - HELP 92222 for the same application.
Common Issues This Part Can Address
- Hard starting caused by worn or fouled spark plugs
- Rough idle from weakened spark output
- Misfire conditions related to plug wear
- Reduced throttle response from inconsistent ignition performance
- Service intervals reached on vehicles using a standard copper/nickel plug design
Installation Notes and Tips
Verify the engine calls for LMAR9G, 92222, or the matching NGK specification before installation. Confirm thread diameter, reach, seat type, and pre-gap against the vehicle service information, especially on Honda Civic and Toyota Corolla applications where ignition specifications can vary by engine code and model year.
Use proper spark plug handling practices, inspect the ignition coil and plug well condition, and torque to the manufacturer’s specification. Check the gap only if the application procedure calls for adjustment.
