NGK D8EA plugs, individual condensers and a bracket-mounted coil pair give you distinct service choices. Read the quantities and application on each listing before deciding how much of the ignition system to replace.
The plug application calls for four D8EA plugs per CB750 and the condenser application for two condensers. Those are per-bike requirements, not described four-plug or two-condenser packages. Keep order quantities separate from the two coils explicitly supplied in the coil set.
Compare a coil assembly with separate components
The featured stock-type coil pair includes brackets and specifies 4.3 ohms primary and 15,000 ohms secondary resistance. If the ignition has been changed, compare its required coil resistance before ordering. A bracket match alone does not establish electrical suitability.
Common questions
How many D8EA plugs does the listing specify?
Four plugs per CB750. That is the application quantity, not a statement that one product order contains four plugs. Check the quantity you intend to replace when completing the order.
What is the difference between the Dyna S Premium and Ultimate packages?
Both include the Dyna S module and Dynatek plug wires. The Premium package supplies two generic 3.3-ohm coils; the Ultimate package supplies two Dynatek-brand 3-ohm coils. Choose by the actual contents rather than assuming the coil brand is the same.
Does the module-only Dyna S product require buying a complete coil kit?
It is offered for stock coils or coils rated at 3 ohms or higher. Verify the fitted coils against the ignition manufacturer’s requirements before choosing the module-only package or adding a separate coil pair.
