Moroso 73800 Ultra Race 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. Engineered to deliver consistent spark energy while resisting the extreme heat and electromagnetic interference found in competitive environments, this wire set features advanced materials and construction techniques.

Key Features:

• Locking stainless steel terminals ensure secure connections that won't vibrate loose
• High-temperature silicone boots protect terminals from heat damage
• Fold-over crimping provides superior electrical contact and mechanical strength
• Silicone jacket protects against heat up to 600°F and resists chemicals and abrasion
• Nickel copper alloy conductor delivers excellent electrical conductivity
• Ferrite impregnated core suppresses electromagnetic interference (EMI)
• Kevlar center core provides exceptional tensile strength and durability
• Conductive polymer coating eliminates voltage leaks and corona discharge

The Ultra 40 design combines low resistance with superior EMI suppression, making it ideal for high-compression engines, forced induction applications, and race vehicles where reliable ignition performance is critical. The multi-layer construction ensures maximum durability in harsh racing conditions.
