The Goodman 10716003 Natural Gas Orifice is a genuine OEM burner spud engineered for the Goodman GKS90703BXAB gas furnace and compatible models. This precision-drilled orifice meters the exact flow of natural gas into the burner, ensuring a clean, efficient flame and correct BTU input. A worn, corroded, or incorrectly sized orifice can cause poor combustion, sooting, delayed ignition, or unsafe operation — making a proper OEM replacement essential.
Genuine OEM 10716003 orifices are drilled to Goodman's exact bore diameter for the model's rated BTU input. Generic orifices may have inconsistent drill sizes, altering the gas flow and combustion quality. For safe, code-compliant firing rates, always use OEM.
Moderate (2/5). Threads into the manifold — shut off gas and power, remove the burner assembly if needed, and thread in the new orifice with a nut driver or wrench. Verify flame quality and manifold pressure after install. Professional installation recommended for gas components.
