Frequently Asked Questions

Will these work with my Harley's ION sensing coil?

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

What makes Moroso Kevlar core better than standard wire?

The DuPont Kevlar core is four times stronger than aramid cores, providing greater pull strength and terminal retention under high vibration.

Can these wires handle high engine temperatures?

Yes. The silicone boots and jacket are rated to withstand heat up to 600°F, and the extra-thick EPDM insulation layer provides superior dielectric strength.

Are these Made in the USA?

Yes — Moroso High Performance ignition wires are manufactured in the USA to exacting quality standards.

Will the terminals stay connected during hard riding?

Yes. The locking stainless steel terminals are engineered to resist vibration disconnect, even under sustained high RPM operation.
