The Goodman 10716005 is a genuine natural-gas burner orifice (spud) for VMS81005CNAA gas furnaces and compatible Goodman/Amana models. The orifice threads into the manifold and meters the precise volume of gas delivered to each in-shot burner. Its drilled bore size sets the BTU input, so using the factory-correct orifice is essential for safe, efficient combustion and a properly shaped flame.
Orifice bore diameter is the single most important dimension on this part. The OEM 10716005 is precision-drilled to Goodman's specification for the model's rated input. Generic or mis-drilled orifices change the gas rate, producing sooty flames, delayed ignition, or over-firing that can crack the heat exchanger. For a gas-metering component, always fit OEM.
Easy (2/5). Shut off gas and power, back the manifold off the burners or unthread the individual orifice, and install the replacement snug (do not over-torque brass). About 20 minutes. Confirm flame color and leak-test the manifold joint after reassembly. Professional installation recommended for gas work.
