The kit centers on the 18-1908 manifold spacer and includes the gaskets needed to seal the connection, so the elbow gasket hunt is eliminated at install time. Each kit ships with one 18-2849-1 elbow gasket and one 18-0897 elbow gasket, matched specifically for use with the 18-1908 spacer and 18-1976-2 riser combination.\u003c\/p\u003e\u003cp\u003eConstruction is metal, matching the durability expected of an exhaust manifold component that sees sustained heat and marine moisture exposure. The kit is packaged as a single unit count, ready to install without sourcing separate gaskets or hardware. It is intended as a direct fit for the riser and spacer combination it is designed for, simplifying maintenance on the exhaust cooling path of applicable I\/O setups.\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 18-1908K\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Type:\u003c\/strong\u003e Manifold Riser Spacer Kit\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Metal\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncluded Components:\u003c\/strong\u003e Manifold spacer 18-1908, (1) elbow gasket 18-2849-1, (1) elbow gasket 18-0897\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUse With:\u003c\/strong\u003e Riser 18-1976-2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUnit Count:\u003c\/strong\u003e 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFit Type:\u003c\/strong\u003e Universal Fit\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 16.5 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 808282159399\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cp\u003eDesigned for use with riser 18-1976-2 on applicable I\/O exhaust cooling systems.\u003c\/p\u003e\u003ch3\u003eReplaces (OEM)\u003c\/h3\u003e\u003cp\u003eNo OEM cross-reference numbers are specified for this kit.\u003c\/p\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat is included in the Sierra 18-1908K kit?\u003c\/strong\u003e The 18-1908K kit includes the 18-1908 manifold spacer along with one 18-2849-1 elbow gasket and one 18-0897 elbow gasket, giving you the spacer and both gaskets needed for the installation in a single package.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat riser does the 18-1908K manifold spacer kit work with?\u003c\/strong\u003e This kit is designed for use with riser 18-1976-2, so it pairs the 18-1908 spacer and its gaskets specifically for that riser.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the 18-1908K a full gasket set or just the spacer?\u003c\/strong\u003e It is a complete kit, not just a bare spacer: the 18-1908 spacer ships together with the 18-2849-1 and 18-0897 elbow gaskets required to seal it in place.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat material is the Sierra 18-1908K spacer made from?\u003c\/strong\u003e The manifold spacer in the 18-1908K kit is made of metal, consistent with the durability needed for an exhaust manifold cooling component.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does the 18-1908K kit weigh?\u003c\/strong\u003e The Sierra 18-1908K Manifold Riser Spacer Kit weighs 16.5 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow many units come in one 18-1908K package?\u003c\/strong\u003e Each 18-1908K package is a single unit count, containing one manifold spacer and the two elbow gaskets listed for that kit.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eAre there OEM cross-reference numbers for the 18-1908K kit?\u003c\/strong\u003e No OEM cross-reference or replacement numbers are specified for the 18-1908K kit itself; it is identified by its own part number, 18-1908K.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDo I need to buy separate gaskets for the 18-1908K spacer?\u003c\/strong\u003e No, separate gaskets are not needed: the 18-1908K kit already includes one 18-2849-1 elbow gasket and one 18-0897 elbow gasket alongside the manifold spacer.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is the UPC for the Sierra 18-1908K kit?\u003c\/strong\u003e The Sierra 18-1908K Manifold Riser Spacer Kit carries UPC 808282159399.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the Sierra 18-1908K compatible with other risers besides 18-1976-2?\u003c\/strong\u003e The 18-1908K kit is specified for use with riser 18-1976-2; compatibility with other risers is not indicated.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat brand makes the 18-1908K manifold spacer kit?\u003c\/strong\u003e The 18-1908K Manifold Riser Spacer Kit is made by Sierra.\u003c\/p\u003e","brand":"Sierra","offers":[{"title":"Default Title","offer_id":48988089155803,"sku":"SIE-18-1908K","price":388.21,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/Untitled-1__39046.1753840675.500.750.jpg?v=1785188246","url":"https:\/\/www.goodvibesmarina.com\/products\/sierra-18-1908k-3-inch-manifold-riser-spacer-kit-replaces-mercruiser-807476a6-93320a5-for-18-1957-2-manifold","provider":"Good Vibes Marina","version":"1.0","type":"link"}
