Product Details

Built for consistent ignition performance, the NGK 7928 spark plug uses a copper core to promote efficient heat transfer and a nickel firing tip for reliable spark delivery. The standard single-ground-electrode layout and flat-seat construction make it a practical replacement choice for engines that call for the B10ES specification. This part cross-references Autolite 4062 and AMS Automotive 4051 for the same application.

For fitment-based searches, this spark plug is a direct match for vehicles that specify NGK B10ES or equivalent service parts. It is commonly searched for Honda Civic spark plug replacement and Toyota Corolla spark plug replacement applications, as well as other make/model combinations that require the same thread, reach, and heat range. The part number 7928 should be verified against the vehicle’s original specification before installation.

Common Issues This Part Can Address

• Hard starting caused by worn or fouled spark plugs
• Rough idle from weak or inconsistent spark output
• Misfire conditions tied to aged ignition components
• Reduced throttle response from degraded plug performance
• Maintenance replacement for engines calling for B10ES specification plugs

Installation Notes and Tips

Confirm the engine calls for a flat-seat spark plug with a 14.00 mm thread diameter, .75 reach, and the correct heat range before installation. Check the gap specification for the application and verify the terminal style matches the ignition lead or coil connection. For best results, install on a cool engine and torque to the manufacturer’s specification.

When searching by vehicle, use terms such as Honda Civic spark plug 7928 or Toyota Corolla B10ES spark plug to narrow the correct application. Always compare the old plug’s dimensions and service part number to the replacement before final fitment.
