Moroso 73614 Ultra Race Wire Spark Plug Wire Set - 40

The Moroso Ultra 40 Race Wire is a high-performance spark plug wire designed for racing and high-output engines where durability and consistent ignition are critical. Built with premium materials and race-proven construction, this wire delivers reliable spark energy while withstanding the extreme heat and vibration of competition environments.

Key Features:

• Nickel Copper Alloy Conductor: Provides excellent conductivity with minimal resistance for maximum spark energy transfer
• Ferrite Impregnated Core: Suppresses electromagnetic interference (EMI) to prevent radio frequency noise and protect sensitive electronics
• Kevlar Center Core: Reinforced strength prevents wire breakage under high-vibration racing conditions
• Conductive Polymer Coating: Ensures consistent electrical performance throughout the wire's length
• High Temperature Silicone Jacket and Boots: Superior heat resistance protects against header heat and engine bay temperatures
• Locking Stainless Steel Terminals: Secure, corrosion-resistant connections that won't back out under vibration
• Fold Over Crimping: Professional-grade terminal attachment for reliable electrical contact

Ideal for street/strip applications, drag racing, road racing, and high-performance street engines where ignition reliability cannot be compromised. The Ultra 40's combination of low resistance and high-temperature protection makes it an excellent choice for supercharged, turbocharged, and naturally aspirated engines operating in demanding conditions.
