It is sold as a package of 2 gaskets, giving a complete matched set for a single intake manifold installation or reseal job. The set is built as a direct replacement for OEM part number 16.50-00232, so it installs in place of the original equipment gasket without modification.\u003c\/p\u003e\u003cp\u003eThis gasket set is designed for MCM\/MIE GM V-8 engines in 305 and 350 cubic inch displacement, 1975 and newer, and also fits OMC 5.7L engines from the 1994 and 1996-1997 model years. Boat owners and marine technicians use it during intake manifold removal, engine rebuilds, or when addressing a leaking or failed intake gasket. Confirming your engine matches the GM V-8 305\/350 cid or OMC 5.7L applications listed, or cross-referencing to OEM 16.50-00232, is the best way to verify fit before ordering.\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 18-0868\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Type:\u003c\/strong\u003e Intake Manifold Gasket Set\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackaging:\u003c\/strong\u003e Package of 2 gaskets\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.31 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Dimensions:\u003c\/strong\u003e 0.39 x 0.39 x 0.39 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 030999755131\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM Cross Reference:\u003c\/strong\u003e 16.50-00232\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eMCM\/MIE GM V-8 305 and 350 cid engines, 1975 and newer\u003c\/li\u003e\n\u003cli\u003eOMC 5.7L engines, 1994, 1996-1997\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eReplaces (OEM)\u003c\/h3\u003e\u003cul\u003e\u003cli\u003e16.50-00232\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat OEM part number does the Sierra 18-0868 gasket set replace?\u003c\/strong\u003e The Sierra 18-0868 intake manifold gasket set replaces OEM number 16.50-00232.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow many gaskets are included in the 18-0868 set?\u003c\/strong\u003e This set is sold as a package of 2 gaskets, providing a complete matched pair for an intake manifold installation.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhich engines does the Sierra 18-0868 gasket set fit?\u003c\/strong\u003e It fits MCM\/MIE GM V-8 engines in 305 and 350 cubic inch displacement (1975 and newer), as well as OMC 5.7L engines from 1994 and 1996-1997.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWill this gasket set fit an OMC 5.7L engine?\u003c\/strong\u003e Yes, the 18-0868 set is designed to fit OMC 5.7L engines from the 1994 and 1996-1997 model years.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes the 18-0868 fit MerCruiser MCM\/MIE engines?\u003c\/strong\u003e Yes, it fits MCM\/MIE GM V-8 305 and 350 cid engines built in 1975 and newer.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does the Sierra 18-0868 gasket set weigh?\u003c\/strong\u003e The 18-0868 intake manifold gasket set weighs 0.31 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat are the dimensions of the 18-0868 gasket set?\u003c\/strong\u003e The set measures 0.39 x 0.39 x 0.39 inches as packaged.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the Sierra 18-0868 an OEM part or an aftermarket replacement?\u003c\/strong\u003e It is an aftermarket gasket set manufactured by Sierra, engineered as a direct replacement for OEM 16.50-00232.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is included when I order the 18-0868 gasket set?\u003c\/strong\u003e You receive a package of 2 intake manifold gaskets, the complete set needed for one intake manifold installation.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow do I confirm the 18-0868 is the correct gasket for my engine?\u003c\/strong\u003e Match your engine to MCM\/MIE GM V-8 305 or 350 cid (1975 and newer) or OMC 5.7L (1994, 1996-1997), or cross-reference to OEM number 16.50-00232.\u003c\/p\u003e","brand":"Sierra","offers":[{"title":"Default Title","offer_id":48988085813467,"sku":"SIE-18-0868","price":31.38,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/SIE-18-0868_lg__64758.1558119292.500.750.jpg?v=1785188366","url":"https:\/\/www.goodvibesmarina.com\/products\/sierra-18-0868-marine-intake-manifold-gasket-set-pkg-of-2-replaces-omc-3854269-mercury-27-17145-fits-gm-v-8-305-350-cid-mercruiser-omc-5-7l","provider":"Good Vibes Marina","version":"1.0","type":"link"}
