Frequently Asked Questions

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

Yes — Moroso Ultra 40 wires are 100% compatible with Harley ION sensing coils on virtually all late-model bikes.

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

40 ohms per foot is class-leading resistance that optimizes spark energy transfer while protecting sensitive ignition electronics.

Can these handle high heat near the cylinders?

Yes — silicone boots and jacket are rated to withstand continuous heat up to 600°F, and the extra-thick EPDM layer adds dielectric strength.

Why is the Kevlar core important?

DuPont Kevlar is four times stronger than standard aramid cores, providing better durability and reduced chafing over the wire's lifetime.

How many wires are in this set?

This is a 40-piece set for complete ignition system coverage.
