Rather than sourcing individual ignition components separately, this kit bundles everything needed to refresh the ignition system in one part number, helping restore reliable spark and smoother running to an aging or worn distributor setup.\u003c\/p\u003e\u003cp\u003eInside the kit, boat owners get one each of four core ignition components: a contact set (breaker points), a condenser, a rotor, and a distributor cap. Each component is manufactured to meet or exceed the original equipment part it replaces, and is built to hold up in the demanding marine environment where heat, vibration, and moisture accelerate ignition component wear. Replacing these parts together as a kit ensures the contact set gap, condenser capacitance, and rotor\/cap contact surfaces are all fresh at the same time, which is the recommended approach for single point ignition maintenance since these wear items affect each other's performance.\u003c\/p\u003e\u003cp\u003eThis kit is designed for engines and applications using the Delco In-Line 4, single point ignition configuration. It is backed by Sierra's Customer Satisfaction Warranty, which covers defects in workmanship and materials for the useful life of the product.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Sierra\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number:\u003c\/strong\u003e 18-5268\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Type:\u003c\/strong\u003e Ignition Tune-Up Kit\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEngine Application:\u003c\/strong\u003e Delco In-Line 4, Single Point Ignition (GM 4 Cyl.)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eKit Contents:\u003c\/strong\u003e 1 Contact Set (18-5311), 1 Condenser (18-5345), 1 Rotor (18-5418), 1 Distributor Cap (18-5385)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.52 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Dimensions:\u003c\/strong\u003e 8 x 6 x 3 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eExterior Finish:\u003c\/strong\u003e Machined\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 808282234034\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eDelco In-Line 4 cylinder engines with single point ignition\u003c\/li\u003e\n\u003cli\u003eGM 4 Cyl.
