The Goodman 10716005 Natural Gas Burner Orifice (spud) is a precision-drilled OEM part for AMS80603AXAB gas furnaces and compatible Goodman/Amana models. Threaded into the manifold ahead of each burner, the orifice meters the exact volume of natural gas required for clean, complete combustion at the furnace's rated input. A worn, corroded, or incorrectly sized orifice causes lazy or noisy flames, sooting, and reduced efficiency — replacing it with the factory-spec part restores proper flame characteristics.
OEM vs. Generic: Orifice bore size directly controls gas input and safety. The OEM 10716005 is drilled to Goodman's exact specification for this furnace and altitude rating. Generic spuds may be mismarked or drilled off-size, leading to over-firing, incomplete combustion, or CO risk. For gas metering, always choose OEM and verify the marked size against the rating plate.
Install difficulty: Easy to moderate (2/5). Shut off gas and power, remove the manifold or unthread the orifice with a socket, and replace. Confirm flame quality and manifold pressure after installation.
