The Goodman 10716003 is a genuine OEM natural-gas burner orifice (spud) for the WGGE4330A045MAB gas furnace and compatible Goodman/Amana models. This precision-drilled brass fitting threads into the manifold and meters the exact volume of natural gas delivered to each burner, setting the furnace's rated BTU input. A correctly sized orifice is essential for a clean, blue flame and efficient, safe combustion.
This is a genuine Goodman OEM orifice bored to the precise drill size your furnace was rated for. Generic orifices can vary by a few thousandths of an inch, which under- or over-fires the burners and leads to sooting, delayed ignition, or high fuel bills. Because orifice sizing is tied directly to safe combustion, matching OEM is the reliable path. Do not substitute an LP (propane) orifice on a natural-gas furnace.
Easy (2 of 5). About 20–30 minutes: shut off gas and power, remove the burner assembly or manifold, unscrew the old orifice with the correct wrench, and thread in the exact-match replacement — do not overtighten the soft brass. Verify no gas leaks with a soap-bubble test and confirm the flame is fully blue before returning the furnace to service. Gas work is best left to a licensed HVAC technician.
