NGK 92143 Spark Plug

NGK BPR6HS BLYB Spark Plug

The NGK 92143 is a standard carded spark plug built for small-engine and powersports applications that call for a 14 mm thread, 0.5 in. reach, and flat seat design. It uses a copper core center electrode, nickel ground electrode materials, and a 5,000 ohm resistor for stable ignition performance.

Compatible with a wide range of Honda, Yamaha, Suzuki, and Hyosung applications, this spark plug is a direct service part for engines that specify the NGK BPR6HS BLYB configuration. The removable nut terminal and 13/16 in. hex size support common service-tool access, while the pre-gapped 0.028 in. specification matches many listed applications.

• Standard spark plug design for routine ignition service
• Copper core center electrode for consistent electrical transfer
• Nickel ground electrode and standard ground configuration
• 5,000 ohm resistor type for reduced electrical noise
• Flat seat, 14 mm thread, and 0.5 in. reach

Application Details

This spark plug is used in engines that require the NGK 92143 / BPR6HS BLYB specification. Fitment includes 2006-2007 Hyosung TE50, 1983-2006 Yamaha PW80, 1988-1990 Honda SB50 Elite, 1983-1987 Honda NB50 Aero, 1984-1987 Honda NQ50 Spree, 1983-1986 Yamaha CA50 Riva, and 1973-1977 Suzuki RV90. It also fits additional Honda, Yamaha, and Suzuki models listed in the fitment table, including several Honda Aero, Elite, and Gyro applications.

This part cross-references Champion Spark Plug (e.g., 327, 934M) for the same application.

• Helps restore reliable spark when the original plug is worn or fouled
• Addresses hard starting caused by incorrect gap or degraded electrodes
• Supports smoother combustion in engines specified for this heat range
• Replaces plugs with the same thread, reach, seat, and terminal style

Installation Notes

Verify the engine calls for NGK 92143 or BPR6HS BLYB before installation. Set the gap to the vehicle specification when required; several listed applications call for 0.028 in., while some Yamaha applications specify 0.024 in. Use the correct 13/16 in. spark plug socket and confirm the removable nut terminal matches the ignition lead connection.
