Rather than sourcing each component separately, this kit bundles all three into one part number, simplifying maintenance for boat owners and marine technicians servicing Bosch 4 cylinder ignition systems.\u003c\/p\u003e\u003cp\u003eThe contact set (18-5305) handles the make-and-break switching that fires the ignition coil, the condenser (18-5349) suppresses arcing across the points to protect them from premature wear, and the rotor (18-5428) directs high voltage from the coil to the correct spark plug wire terminal inside the distributor cap. All three parts are engineered to match or exceed the performance of the original equipment components they replace, restoring smooth, reliable ignition timing and helping prevent misfires, hard starting, and rough idle caused by worn points, a failing condenser, or a pitted rotor.\u003c\/p\u003e\u003cp\u003eThis kit is designed to fit Flame Thrower distributors 18-5481, 18-5482, 18-5483, 18-5477, 18-5478, and 18-5479, making it a straightforward match for boats already equipped with one of these distributors. The components are finished in white plastic housings for the rotor and contact assembly, keeping the parts easy to identify during installation.\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 18-5284\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Name:\u003c\/strong\u003e Tune Up Kit\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEngine Application:\u003c\/strong\u003e Bosch 4 cylinder\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eKit Contents:\u003c\/strong\u003e Contact Set (18-5305), Condenser (18-5349), Rotor (18-5428)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor:\u003c\/strong\u003e White\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Plastic\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eContact Material:\u003c\/strong\u003e Copper\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.13 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 808282105822\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cul\u003e\u003cli\u003eFlame Thrower Distributors: 18-5481, 18-5482, 18-5483, 18-5477, 18-5478, 18-5479\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eReplaces (OEM)\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e243799 (contact set)\u003c\/li\u003e\n\u003cli\u003e1306169 (contact set)\u003c\/li\u003e\n\u003cli\u003e243460 (contact set)\u003c\/li\u003e\n\u003cli\u003e841262 (condenser)\u003c\/li\u003e\n\u003cli\u003e243903 (rotor)\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat is included in the Sierra 18-5284 Tune-Up Kit?\u003c\/strong\u003e The kit contains three components: an 18-5305 contact set, an 18-5349 condenser, and an 18-5428 rotor, covering the main wear parts needed for a distributor tune-up.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhich distributors does the 18-5284 kit fit?\u003c\/strong\u003e It is designed to fit Flame Thrower distributors 18-5481, 18-5482, 18-5483, 18-5477, 18-5478, and 18-5479.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat OEM part numbers does this kit replace?\u003c\/strong\u003e The 18-5284 kit's contact set replaces OEM numbers 243799, 1306169, and 243460, the condenser replaces OEM number 841262, and the rotor replaces OEM number 243903.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the Sierra 18-5284 kit compatible with 4 cylinder Bosch ignition systems?\u003c\/strong\u003e Yes, this tune-up kit is built for Bosch 4 cylinder engine applications.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does the 18-5284 Tune-Up Kit weigh?\u003c\/strong\u003e The complete kit weighs 0.13 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat color are the components in the 18-5284 kit?\u003c\/strong\u003e The rotor and related plastic components in this kit are white.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat material is the rotor made from?\u003c\/strong\u003e The rotor housing is made from plastic, with copper used for the contact material in the contact set.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDo I need to replace all three parts in the kit at once?\u003c\/strong\u003e The 18-5284 kit is sold as a complete set with the contact set, condenser, and rotor bundled together for a full distributor service, rather than as individually purchasable pieces.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes the Sierra 18-5284 meet original equipment performance standards?\u003c\/strong\u003e Sierra states this tune-up kit's components meet or exceed the performance of the original equipment parts they replace.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCan I use the 18-5284 kit for a routine ignition tune-up?\u003c\/strong\u003e Yes, this kit is intended for routine maintenance, supplying fresh points, condenser, and rotor to restore reliable ignition performance in Flame Thrower distributors.\u003c\/p\u003e","brand":"Sierra","offers":[{"title":"Default Title","offer_id":48988205842651,"sku":"SIE-18-5284","price":40.71,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/SIE-18-5284_lg__54323.1558126907.500.750.jpg?v=1785188317","url":"https:\/\/www.goodvibesmarina.com\/products\/sierra-18-5284-marine-tune-up-kit-for-bosch-4-cylinder-distributors-volvo-penta-contact-set-condenser-rotor-replaces-oem-241664-243460-243799-1306169","provider":"Good Vibes Marina","version":"1.0","type":"link"}
