It is a direct-fit replacement designed to route exhaust gases away from the engine and into the riser and exhaust hose system, maintaining proper cooling water flow and exhaust flow through the powerhead.\u003c\/p\u003e\u003cp\u003eThis manifold is designed to work as part of a complete exhaust system. It pairs with riser gasket 18-0943-2 to seal the connection between the manifold and riser, and with mounting kit 18-8507 for a proper installation. It also cross-references to alternate manifold part number 18-1986-1, so buyers researching either number can confirm they are looking at compatible hardware for the same engine family.\u003c\/p\u003e\u003cp\u003eBecause it fits many GM and Ford applications using the center rise manifold layout, the 18-1848 is a common replacement choice when an original manifold has cracked, corroded, or otherwise failed. At 32 pounds, it is built to the same general weight and duty class as the OEM hardware it replaces.\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 18-1848\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Type:\u003c\/strong\u003e Exhaust Manifold\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFitment:\u003c\/strong\u003e Fits many GM and Ford center rise manifolds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompanion Riser Gasket:\u003c\/strong\u003e 18-0943-2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompanion Mounting Kit:\u003c\/strong\u003e 18-8507\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAlternate Manifold Reference:\u003c\/strong\u003e 18-1986-1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 32 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 808282266431\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eFits many GM and Ford engines with a center rise manifold configuration\u003c\/li\u003e\n\u003cli\u003eUse with riser gasket 18-0943-2 and mounting kit 18-8507 for a complete installation\u003c\/li\u003e\n\u003cli\u003eAlternate manifold reference: 18-1986-1\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat engines does the Sierra 18-1848 exhaust manifold fit?\u003c\/strong\u003e The Sierra 18-1848 fits many GM and Ford engines that use a center rise manifold configuration.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes the 18-1848 come with a riser gasket?\u003c\/strong\u003e No, the manifold itself does not include the riser gasket.
