Moroso 27166 Suppression Core Ignition Wire Set for Harley-Davidson FXD Dyna

The Moroso 27166 is a high-performance suppression core ignition wire set engineered as a direct OEM replacement for Harley-Davidson FXD and FXDWG Dyna models (1999–2017). Designed to meet or exceed original equipment specifications, this wire set delivers reliable spark delivery and improved ignition performance over worn stock wires.

Key Features:

• Suppression core construction — glass center core coated with conductive latex for reliable, consistent spark transmission
• High-temperature EPDM jacket — resists heat, abrasion, and chafing for long service life
• Strong mesh tape layer — separates core from outer jacket and adds pull strength to prevent damage during installation or removal
• Silicone plug boots — rated to withstand temperatures up to 600°F, ensuring a secure and durable connection at the plug
• Direct OEM replacement — plug-and-play fitment with no modifications required
• Suppression core design reduces electromagnetic interference (EMI) with onboard electronics

The Moroso 27166 is a cost-effective upgrade that restores or improves upon factory ignition performance, making it an ideal choice for routine maintenance or performance tuning on Harley-Davidson Dyna platform motorcycles.
