Detailed Description

NGK 93427, also identified as BPR8ES-6, is a standard spark plug engineered to match the listed Cobra applications. The plug combines a copper center electrode core with nickel tip materials and a single ground electrode, while the removable nut terminal supports common ignition wire connections. Its heat range 8 specification, flat seat design, and 13/16-inch hex size align with the published service dimensions.

NGK is known for OE-level spark plug manufacturing and broad coverage across automotive, motorcycle, marine, and small engine applications. This part cross-references 92070-0707D for the same application.

What It Helps Address

• Misfires caused by worn or fouled spark plug electrodes.
• Hard starting related to weak ignition output.
• Rough idle from inconsistent spark delivery.
• Reduced combustion efficiency from incorrect plug gap or heat range.

Installation Notes and Tips

Verify the plug gap, thread reach, seat type, and heat range before installation. Use the published 0.024-inch gap for the listed applications and confirm the removable nut terminal matches the ignition lead connection. Always follow the service procedure for tightening and inspection.

Quality Assurance

NGK manufactures spark plugs to original equipment standards and supports broad OE coverage in North America. Part number 93427 reflects NGK's standard spark plug catalog identification for the listed applications.
