Frequently Asked Questions

Will these work with my Harley's ION ignition system?

Yes — these wires are 100% compatible with Harley's ION sense coils used on virtually all late-model bikes.

What's the resistance rating and why does it matter?

40 ohms per foot. Lower resistance improves spark energy transfer for better ignition and performance.

Are these made in the USA?

Yes. Moroso High Performance wires are manufactured and assembled in the USA.

Do the silicone boots really handle 600 degrees?

Yes — the high-temperature silicone construction withstands up to 600°F without degradation or cracking.

What makes these different from cheaper wire sets?

DuPont Kevlar core (four times stronger than standard Aramid), locking stainless steel terminals, and nickel copper conductors for superior spark energy and durability under vibration.
