• Spiral-wound stainless nickel alloy conductor over a conductive latex-coated, heavy-duty fiberglass core for superior EMI/RFI suppression
• Fiberglass reinforcing braid for added structural durability
• High-temperature EPDM outer jacketing for excellent electrical insulation and long service life
• 100% silicone plug boots rated to withstand temperatures up to 600°F, with moisture resistance and heat/chafe protection
• Snap-lock spark plug terminals for a secure, vibration-resistant connection
• Eliminates interference with on-board electronics and supports static-free audio system performance
• Sold as a complete set — includes both wires pre-terminated at the plug end
• Each wire is individually tested for continuity, resistance, electrical conductivity, and dielectric strength after termination

The Moroso Blue Max Spiral Core wire set is the trusted choice for Harley-Davidson Dyna platform owners who demand race-proven ignition technology on the street. Built in the USA with premium materials, these wires meet the exacting standards Moroso has upheld since 1968.
