Frequently Asked Questions

How many 5.2-ohm dual-output ignition coils are included and required for the compatible Honda CB four-cylinder models?

One dual-output coil is included. The listed Honda CB four-cylinder ignition systems use two dual-output coils, so two are required to replace both coils on one motorcycle.

What plug wires and caps are required with performance coil 07-9973?

The coil requires 7mm high-tension spark-plug wire and 5K-ohm spark-plug caps, both sold separately. Coil mounting hardware is included; confirm that the ignition system is compatible with the coil's 5.2-ohm primary and 17K-ohm secondary resistance.

Can the ignition be powered with one output of this dual-output coil disconnected?

No. Do not crank or operate the ignition with either spark-plug output disconnected. Both high-tension leads must terminate at correctly installed spark plugs because an open secondary circuit can immediately damage the coil.
