Restoring reliable spark delivery starts with a fresh distributor cap and rotor, and this kit supplies both in one package: a Sierra 18-5352 Distributor Cap and a Sierra 18-5403 Rotor, matched specifically to Prestolite Electronic V-8 ignition setups. Worn or corroded caps and rotors are a common source of hard starting, misfires, and rough idle in marine engines, and replacing them together as a matched set helps ensure consistent electrical contact and even spark distribution across all cylinders.\u003c\/p\u003e\u003cp\u003eEach component in the kit meets or exceeds the performance of the original equipment part it replaces, giving boat owners and marine technicians a straightforward, fit-specific way to service the ignition system without mixing mismatched parts from different suppliers. Because ignition components vary by engine configuration, this kit is built specifically for Prestolite Electronic V-8 applications; buyers should confirm their engine's ignition type before ordering to ensure proper fit.\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 18-5279\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIgnition Type:\u003c\/strong\u003e Prestolite Electronic\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEngine Configuration:\u003c\/strong\u003e V-8\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eKit Contents:\u003c\/strong\u003e 1 Distributor Cap (Sierra 18-5352), 1 Rotor (Sierra 18-5403)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Dimensions:\u003c\/strong\u003e 3 x 6 x 8.13 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.45 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 808282105082\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cul\u003e\u003cli\u003eV-8 marine engines equipped with Prestolite Electronic ignition systems\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eReplaces (OEM)\u003c\/h3\u003e\u003cul\u003e\u003cli\u003eCDI E66-0029\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat engines does the Sierra 18-5279 Tune Up Kit fit?\u003c\/strong\u003e The Sierra 18-5279 Tune Up Kit is designed for marine V-8 engines equipped with a Prestolite Electronic ignition system.
