Moroso 73657 Ultra Race Spark Plug Wire Set - 40

The Moroso Ultra 40 Race Wire delivers professional-grade ignition performance for high-performance and racing applications. Engineered with advanced materials and construction techniques, this spark plug wire combines superior conductivity with exceptional heat and EMI resistance.

Key Features:

• Locking stainless steel terminals with fold-over crimping ensure secure, vibration-resistant connections that won't pull loose under racing conditions
• Nickel copper alloy conductor provides excellent electrical conductivity with low resistance for consistent spark delivery
• Ferrite impregnated core with Kevlar center core offers superior tensile strength and effective EMI/RFI suppression
• Conductive polymer coating eliminates voltage leakage and corona discharge
• High-temperature silicone jacket and boots protect against extreme heat, oil, and chemicals commonly found in racing environments

Built to withstand the demanding conditions of competitive racing, the Ultra 40 Race Wire features multiple layers of protection and shielding to maintain consistent ignition performance. The premium silicone construction resists temperatures that would destroy conventional wires, while the advanced core design ensures reliable spark energy transfer to the plugs.
