The set is engineered for both conventional and electronic distributor systems, giving it broad coverage across compatible Chrysler powerheads. Each wire uses a mag\/wire wound core that delivers maximum voltage to the plugs while suppressing radio frequency interference (RFI) and electromagnetic interference (EMI), protecting sensitive onboard electronics from ignition noise.\u003c\/p\u003e\u003cp\u003eCorrosion resistant stainless steel terminals are used at both the spark plug and distributor connections for reliable, long-term conductivity in the marine environment. A kevlar-reinforced conductor core adds durability and resistance to heat and vibration, while premium silicone jacketing and silicone boots shield the wires from high underhood temperatures. The distributor end uses moisture-proof, molded insulators to keep out water intrusion, and a high-quality conductive center carrier reinforcement maintains conductor integrity over the life of the set.\u003c\/p\u003e\u003cp\u003eThe set includes one coil wire and eight spark plug wires cut to factory-matched lengths for a proper fit across the compatible engines.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e
