Common questions
Are these ignition wires compatible with my Twin Cam Dyna?
Yes, this Moroso Ultra 40 set is specifically designed for 1999-2017 Harley-Davidson Dyna models with ION sensing ignition coils. Please confirm your exact year and model using our Shop by Bike tool.
Do I need to make any modifications to install these wires?
These wires are designed as a direct replacement for your factory wires and are 100% compatible with Harley's ION sensing ignition coils, making installation straightforward.
Will using these wires require a new dyno tune?
Upgrading ignition wires typically does not necessitate a new dyno tune, as they optimize spark delivery rather than changing fuel maps or timing directly. However, for heavily modified engines, a professional tune always ensures peak performance.
