Frequently Asked Questions

How many NGK D8EA spark plugs are included and required?

One NGK D8EA is included. The compatible Honda CB750 models use four spark plugs, so four are required for a complete engine-wide replacement.

What type of spark plug is NGK D8EA?

D8EA is the conventional non-resistor NGK plug identified as the original-type standard plug for the named CB750 applications. Match the complete NGK code and specified gap.

Can a similar D-series plug or different heat range be substituted?

Do not substitute by thread appearance alone. Use the Honda service information and current NGK application data to confirm plug type, resistance and heat range for the exact model and operating conditions.
