• Rough idle related to inconsistent combustion.
• Misfire concerns tied to plug wear or incorrect gap.
• Loss of throttle response from degraded ignition performance.

Installation Notes

Verify the application before installation and confirm the specified gap for the engine. The fitment notes call for a 0.040-inch spark plug gap on the listed Harley-Davidson applications. Check thread diameter, reach, seat type, and terminal style against the removed plug before service. NGK 96461 should be installed using standard spark plug service procedures and torque specifications for the engine.
