This high-performance, 8.5mm Spark Plug Wire Set (Part #31223) is engineered to deliver maximum ignition energy to your spark plugs while providing superior interference suppression. The universal, cut-to-fit design ensures a perfect, custom-routed fit for nearly any 8-cylinder engine.
Unmatched Performance and Suppression Built with a helically wound copper alloy conductor, these wires feature an ultra-low resistance of just 40-50 ohms per foot, minimizing spark energy loss. A ferro-magnetic impregnated core acts as an RFI choke, effectively suppressing electrical interference (EMI) and protecting your vehicle's sensitive electronics.
Durable, Custom Fitment:
-
Construction: The tough 8.5mm jacket is made from a proprietary blend of silicone and synthetic materials, offering excellent resistance to extreme heat, abrasion, and tearing.
