Frequently Asked Questions
How many NGK DR8EA spark plugs are included and needed?
One NGK DR8EA is included. Every compatible Honda model named here has a four-cylinder engine, so four plugs are needed for a complete engine-wide replacement.
What type of spark plug is the NGK DR8EA?
NGK DR8EA is a conventional resistor spark plug. Match the complete NGK code, because the resistor designation, heat range and suffix are part of the plug specification.
Can a different NGK heat range or similar D-series plug be substituted?
Do not substitute solely because the threads look alike. Use NGK DR8EA only for the listed 1982 CB900C and CB900F plus 1983 CB1000C and CB1100F models, or follow the Honda service information and NGK guidance for a verified alternative.
