The Goodman 10716003 is a genuine OEM natural-gas burner orifice (spud) for WGGE4360A090MAB gas furnaces. Threaded into the manifold, this precision-drilled brass orifice meters the exact volume of natural gas delivered to each burner, setting the furnace's BTU input and ensuring a clean, correctly proportioned flame. A worn, corroded, or incorrectly sized orifice causes poor combustion, sooting, delayed ignition, or reduced heat output. Replacing it with the factory-spec part restores proper firing.
The OEM 10716003 is drilled to the exact orifice diameter Goodman specified for this model's rated input at standard NG pressure. Generic or mis-sized orifices change the gas flow and can over- or under-fire the furnace, creating efficiency loss or a safety hazard. The OEM spud also matches the manifold thread precisely for a leak-free seal.
Rating: Moderate — gas work. Shut off the gas, remove the manifold or back out the orifice, apply approved thread sealant, and leak-check with soap solution before relighting. Because this involves the gas train, we recommend a licensed HVAC technician perform the swap and verify manifold pressure.
