It is built to meet or exceed the quality of the original equipment part it replaces, giving installers a reliable seal that resists the heat and combustion byproducts present at the manifold mounting joint. This gasket is designed for use with Manifold 18-1898, so it is a direct fit when servicing or replacing that manifold assembly.\u003c\/p\u003e\u003cp\u003eAs a mounting gasket, its job is straightforward but critical: maintain a tight, leak-free seal at a high-heat, high-vibration joint so exhaust gases and cooling water stay contained within the manifold system. Sierra manufactures this part to original-equipment specifications, making it a straightforward drop-in replacement for the OEM gasket it supersedes. At 0.23 pounds, it ships as a single-count gasket ready to install during routine manifold service, gasket replacement, or a full exhaust system rebuild.\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 18-0418\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Name:\u003c\/strong\u003e Exhaust Manifold Mounting Gasket\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.23 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor:\u003c\/strong\u003e white\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUnit Count:\u003c\/strong\u003e 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 808282257361\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUse With Manifold:\u003c\/strong\u003e 18-1898\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cul\u003e\u003cli\u003eUse with Manifold: 18-1898\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eReplaces (OEM)\u003c\/h3\u003e\u003cul\u003e\u003cli\u003eCrusader 96653\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat is the Sierra 18-0418 used for?\u003c\/strong\u003e The Sierra 18-0418 is an exhaust manifold mounting gasket that seals the joint where the exhaust manifold mounts, and it is designed for use with Manifold 18-1898.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes the 18-0418 gasket fit manifold 18-1898?\u003c\/strong\u003e Yes, the Sierra 18-0418 mounting gasket is specified for use with Manifold 18-1898.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat OEM part number does the Sierra 18-0418 replace?\u003c\/strong\u003e It replaces Crusader part number 96653.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does the Sierra 18-0418 gasket weigh?\u003c\/strong\u003e 0.23 pounds, per unit.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat color is the Sierra 18-0418 gasket?\u003c\/strong\u003e White is the color of this gasket as supplied by Sierra.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow many gaskets come in one Sierra 18-0418 package?\u003c\/strong\u003e One gasket is included per unit count of the Sierra 18-0418 package.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the Sierra 18-0418 an OEM or aftermarket gasket?\u003c\/strong\u003e It is an aftermarket gasket manufactured by Sierra to meet or exceed the quality of the original equipment part it replaces, specifically Crusader 96653.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is the UPC for the Sierra 18-0418?\u003c\/strong\u003e The UPC is 808282257361.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCan the Sierra 18-0418 be used as a direct replacement without modification?\u003c\/strong\u003e Yes, since it is manufactured to meet or exceed original equipment specifications for the Crusader 96653 gasket it replaces, it installs as a direct replacement with Manifold 18-1898.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the Sierra 18-0418 gasket sold individually?\u003c\/strong\u003e Yes, it is sold as a single gasket, with a unit count of one.\u003c\/p\u003e","brand":"Sierra","offers":[{"title":"Default Title","offer_id":48988074148059,"sku":"SIE-18-0418","price":16.94,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/SIE-18-0418_lg__74798.1558118370.500.750.jpg?v=1785188088","url":"https:\/\/www.goodvibesmarina.com\/products\/sierra-18-0418-exhaust-manifold-mounting-gasket-replaces-mercruiser-27-46820-gm-3852472-fits-454-cu-in-gm-big-block-v8","provider":"Good Vibes Marina","version":"1.0","type":"link"}
