The Goodman 10716005 is a genuine OEM natural gas burner orifice (spud) for the AMS80805CXAC furnace and compatible Goodman/Amana 80% AFUE models. The orifice meters the exact volume of gas delivered to each in-shot burner, controlling BTU input and flame quality. A worn, enlarged, or wrong-size orifice causes over/under-firing, sooting, and efficiency loss, so matching the factory drill size is essential.
The OEM 10716005 is drilled to the precise orifice size for this furnace's rated input at standard manifold pressure. Generic orifices vary in bore tolerance, which can shift BTU output and flame color. For proper combustion and warranty compliance, OEM is the safe choice.
Easy. Shut off gas and power, unthread the old orifice from the manifold with a socket, install the new spud snugly (do not over-torque brass), and check for leaks with soap solution. Verify flame appearance at startup. A quick task for a qualified technician.
