Frequently Asked Questions

Will these work with my Harley's OEM coils?

Yes — Moroso wires are fully compatible with Harley-Davidson ION sensing coils used on virtually all late-model bikes.

What's the core material?

DuPont Kevlar core, which is four times stronger than standard aramid cores and resists heat and vibration damage.

Can these handle high heat?

Yes. Silicone boots are rated to 600°F, and the silicone jacket protects against engine heat and chafing.

Will the terminals stay tight?

Locking stainless steel terminals are designed to resist vibration loosening under high-RPM riding.
