This genuine OEM Goodman 10716005 Natural Gas Burner Orifice (spud) meters the flow of natural gas into the burner assembly of the Goodman VMS80805CNAA furnace. The orifice is precision-drilled to a specific diameter that sets the BTU firing rate for the appliance — using the wrong size directly affects flame quality, efficiency, and safe combustion.
Orifice diameter is a combustion-critical dimension. The OEM 10716005 guarantees the exact drill size Goodman engineered for this furnace's input rating. Generic orifices can be mismarked or over/undersized, causing sooting, delayed ignition, or overheating — always match OEM for a gas metering part.
Moderate (3/5). Requires removing the manifold/burner assembly and threading the orifice to the correct torque. Shut off gas and power first. Recommended for HVAC technicians; verify BTU rating and altitude derating before firing.
