The distributor cap seals and protects the distributor's internal contacts while directing high-voltage spark from the ignition coil to each spark plug in firing order, making it a critical part for reliable engine starting and smooth running. This cap is finished in white with a machined metal construction and uses a twist-on closure for secure, tool-free installation and removal during routine maintenance or tune-ups.\u003c\/p\u003e\u003cp\u003eEach Sierra 18-5358 cap is built to meet or exceed the performance of the original equipment part it replaces, making it a straightforward swap for a cracked, worn, or corroded distributor cap. It is interchangeable with several commonly referenced cross numbers, so boat owners searching by CDI, GLM, Mallory, or Volvo Penta part numbers can confirm they are ordering the correct replacement. One distributor cap is included per package.\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 18-5358\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Type:\u003c\/strong\u003e Distributor Cap\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 Metal\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eExterior Finish:\u003c\/strong\u003e Machined\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eClosure Type:\u003c\/strong\u003e Twist-On\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eItem Dimensions:\u003c\/strong\u003e 0.39 x 0.39 x 0.39 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.48 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 030999319012\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUnit Count:\u003c\/strong\u003e 1\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eVolvo Penta AQ145A\u003c\/li\u003e\n\u003cli\u003eVolvo Penta AQ145B\u003c\/li\u003e\n\u003cli\u003eVolvo Penta AQ151A\u003c\/li\u003e\n\u003cli\u003eVolvo Penta AQ151B\u003c\/li\u003e\n\u003cli\u003eVolvo Penta AQ151C\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eReplaces (OEM)\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eCDI E64-0011\u003c\/li\u003e\n\u003cli\u003eGLM 71480\u003c\/li\u003e\n\u003cli\u003eMallory 9-29410\u003c\/li\u003e\n\u003cli\u003eVolvo Penta 841263\u003c\/li\u003e\n\u003cli\u003eVolvo 841263-7\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat engines does the Sierra 18-5358 distributor cap fit?\u003c\/strong\u003e The 18-5358 distributor cap fits Volvo Penta AQ145A, AQ145B, AQ151A, AQ151B, and AQ151C stern drive engines.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the 18-5358 cap compatible with Bosch distributors?\u003c\/strong\u003e Yes, the Sierra 18-5358 distributor cap is designed for use in Bosch-style distributor applications on the applicable Volvo Penta engines.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat color is this distributor cap?\u003c\/strong\u003e The Sierra 18-5358 distributor cap is white.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is the 18-5358 cap made of?\u003c\/strong\u003e It is made of metal with a machined finish.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat OEM part numbers does the 18-5358 cross reference?\u003c\/strong\u003e Sierra part 18-5358 is interchangeable with CDI E64-0011, GLM 71480, Mallory 9-29410, and Volvo Penta 841263 (also referenced as Volvo 841263-7).\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does the distributor cap weigh?\u003c\/strong\u003e The Sierra 18-5358 distributor cap weighs 0.48 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow does the cap attach to the distributor?\u003c\/strong\u003e It uses a twist-on closure, allowing the 18-5358 cap to be secured or removed without additional tools.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow many caps come in a package?\u003c\/strong\u003e Each order of the Sierra 18-5358 includes one distributor cap.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the Sierra 18-5358 an OEM or aftermarket part?\u003c\/strong\u003e It is an aftermarket replacement built by Sierra to meet or exceed the performance of the original equipment part it replaces, including Volvo Penta 841263.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhen should I replace my distributor cap?\u003c\/strong\u003e A distributor cap like the 18-5358 should be replaced if it is cracked, corroded, or showing carbon tracking, since these conditions cause misfires or hard starting on AQ145 and AQ151 series engines.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes the 18-5358 include the rotor?\u003c\/strong\u003e No, the package includes only the Sierra 18-5358 distributor cap itself; the rotor is a separate component.\u003c\/p\u003e","brand":"Sierra","offers":[{"title":"Default Title","offer_id":48988209774811,"sku":"SIE-18-5358","price":81.09,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/SIE-18-5358_lg__62577.1558129711.500.750.jpg?v=1785189122","url":"https:\/\/www.goodvibesmarina.com\/products\/marine-distributor-cap-for-volvo-penta-stern-drive-with-bosch-ignition-replaces-oem-841263-sierra-18-5358","provider":"Good Vibes Marina","version":"1.0","type":"link"}
