Moroso 73837 Ultra 40 Universal Race Spark Plug Wire Set LS1

The Moroso 73837 Ultra 40 Universal Race Ignition Wire Set is designed specifically for GM LS Series engines with remote coil applications. This high-performance wire features 40 ohms of resistance per foot and incorporates a spiral-wound nickel/copper alloy conductor wrapped at the optimum ratio to produce the highest level of spark energy while producing the lowest level of electromagnetic and radio frequency interference.

Key Features:

• Kevlar core is four times stronger than aramid fiber cores for exceptional tensile strength and dielectric properties
• Universal wire set with 48-inch wire length, unsleeved design with straight boots
• 8.65mm diameter with extra-thick EPDM layer for greater dielectric strength
• High-temperature silicone boots withstand heat up to 600 degrees
• Locking stainless steel plug terminals stay connected under high vibration
• Closely woven fiberglass impregnated with high-voltage-leak resistant silicone adds up to 8,000 volts of extra insulation
• Used in the highest level of racing applications, from dual mag Top Fuel cars through NASCAR

This universal wire set is unsleeved and features red wire construction. All Moroso ignition wires are made in the USA at Moroso Wire Technologies in Philadelphia, PA. The optimized design maximizes energy transfer while minimizing electromagnetic interference (EMI) and radio frequency (RF) interference noise, making it ideal for high-performance and racing applications.
