The Goodman 10716005 natural gas burner orifice (spud) is a genuine OEM metering component for AMS80804BXAC 80% AFUE furnaces. The orifice threads into the manifold and precisely meters natural gas into each in-shot burner. Its drilled bore is sized to deliver the exact BTU input your furnace is rated for — a worn, corroded, or incorrectly drilled orifice causes lazy flames, sooting, or incorrect heat output.
The OEM 10716005 is drilled to the precise orifice size specified for this furnace model, guaranteeing correct gas input and a crisp blue flame. Generic or hand-drilled orifices risk over- or under-firing, which wastes fuel and can produce carbon monoxide. Always match the OEM spec.
Moderate — shut off gas and power, remove the manifold or access the spud, and thread in the new orifice snugly (do not overtighten). Roughly 30 minutes. Leak-check every joint with soap solution and confirm proper flame appearance before leaving the furnace in service. If unsure, use a licensed technician.
