Moroso 73605 Ultra Race Spark Plug Wire Set - 40

The Moroso 73605 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 set provides superior conductivity, electromagnetic interference suppression, and durability under extreme conditions.

Key Features:

• Locking stainless steel terminals ensure secure, vibration-resistant connections that won't back out during operation
• High-temperature silicone boots protect connections from heat damage and provide easy installation and removal
• Fold-over crimping technology creates a permanent, low-resistance connection between terminal and conductor
• Silicone jacket construction withstands extreme heat while providing excellent flexibility and abrasion resistance
• Nickel copper alloy conductor delivers optimal electrical conductivity with minimal voltage loss
• Ferrite impregnated core effectively suppresses electromagnetic interference (EMI) and radio frequency interference (RFI)
• Kevlar center core provides exceptional tensile strength and prevents wire stretch during installation
• Conductive polymer coating maintains consistent resistance throughout the wire's length

Designed for racing engines and high-performance street applications where reliability and consistent spark delivery are critical. The Ultra 40 designation indicates approximately 40 ohms per foot of resistance, ideal for electronic ignition systems requiring EMI suppression without sacrificing performance.
