The Goodman 10716005 is a genuine OEM natural-gas burner orifice (spud) for the VMS80805CXAA furnace. The orifice threads into the manifold and meters the precise gas flow into each in-shot burner, setting the furnace's BTU input. The drill size is matched to natural gas at the furnace's rated manifold pressure — using the wrong orifice over- or under-fires the burners and can cause sooting or poor efficiency.
The OEM orifice carries the exact factory drill size for the certified input rating. Generic or LP orifices installed on natural gas will misfire the burners and create a safety hazard. Always match the orifice to the fuel and the furnace's rating plate.
Moderate (2/5). Requires removing the manifold or accessing the orifice port and threading in the new spud without cross-threading. Shut off gas and power, then leak-test all connections after installation.
