Moroso 73668 Ultra Custom Fit Spark Plug Wire Set - 40

The Moroso 73668 Ultra 40 Custom Fit Wire Set delivers high-performance ignition with advanced materials engineered for extreme conditions. Designed for custom applications, this wire set features a sophisticated multi-layer construction that provides superior conductivity while resisting heat, EMI, and electrical interference.

Advanced Construction Features:

• Nickel Copper Alloy Conductor: Provides excellent electrical conductivity with minimal resistance for strong, consistent spark delivery
• Ferrite Impregnated Core: Suppresses electromagnetic interference (EMI) to prevent ignition noise and protect sensitive electronics
• Kevlar Center Core: High-tensile strength core resists stretching and tearing during installation and under vibration
• Conductive Polymer Coating: Inner coating ensures continuous electrical contact while reducing resistance
• High Temperature Silicone Jacket: Outer layer protects against extreme heat, oil, chemicals, and abrasion
• Locking Stainless Steel Terminals: Secure connection with fold-over crimping prevents spark blow-out and ensures reliable contact
• High Temperature Silicone Boots: Durable boots protect connections from moisture, heat, and contaminants

The Ultra 40 series wire sets are ideal for racing applications, high-performance street engines, and custom builds where precise wire routing is required. The combination of low resistance, excellent shielding, and durable construction ensures reliable ignition performance in demanding conditions.
