Frequently Asked Questions

Are these compatible with my late-model Harley ignition coils?

Yes — 100% compatible with Harley's ION sensing coils used on virtually all late-model Dyna bikes.

Will these work on a pre-1999 Dyna?

This set is engineered for 1999-2017 Dyna models. Older models may use different coil types — verify your coil before ordering.

What's included in the 40-set?

One complete ignition wire set with all wires needed for your Dyna's firing order.

How do these compare to OEM Harley wires?

Moroso wires use a Kevlar core four times stronger than standard aramid, nickel copper conductors, and 40 ohms resistance for improved spark delivery compared to many factory wires.

Can I use these if I've upgraded my ignition system?

These are built for standard Harley ION coils. If you've installed an aftermarket ignition system, verify compatibility with that manufacturer first.
