Each wire uses a Kevlar core paired with a durable stainless steel wound conductor, delivering maximum horsepower and consistent engine performance while resisting the vibration and heat stress typical of marine engine bays. Premium silicone jacketing and boots provide high-temperature protection at the plug and distributor connections, and the terminals are corrosion-resistant stainless steel for reliable conductivity in a marine environment.\u003c\/p\u003e\u003cp\u003eThis set is part of Sierra's MAGFORCE ignition wire line, engineered to be \"Electronics Friendly\" -- it shields onboard electronic devices and electronic engine controls from RFI and EMI interference while still delivering maximum voltage to the plugs. The distributor end is moisture-proof and molded for a secure, sealed connection, and the exact-fit design is intended for straightforward installation without custom trimming or fitting.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e
