The CDI Electronics Spark Plug Wire Set maximizes energy transmission, EMI suppression, and radio and electronic ignition performance. High-voltage protection is provided by extensive EPDM insulation—a silicone jacketed wire of exceptional quality. Thunderbolt 8 Cylinder engines are compatible.

When compared to seven prominent manufacturers, CDI Electronics' High-Performance Spark Plug Wire sets provide more incredible spark energy, better EMI suppression, and more muscular dielectric strength; CDI Electronics outperformed them all. They have the best capacitance, inductance, and resistance for maximal energy transfer. Their optimum electrical qualities provide the finest EMI suppression for peak radio-electronic ignition performance. They also give adequate insulation by covering thick EPDM with a silicone coating (Ethylene Propylene Diene Monomer).

Note: This product is not permitted for use on cars that must fulfill CARB criteria and are registered in California or other states that follow CARB rules, such as New York and Maine.

Key features:

• Maximum energy transfer requires optimal capacitance, inductance, and resistance.

• Ideal electrical qualities give the optimum EMI suppression for optimal radio and electronic ignition performance.

• For optimum insulating performance, use a premium silicone jacket over thick EPDM.
