The Goodman 10716005 Natural Gas Orifice (burner spud) is the genuine OEM metering component for VMS80804BXAA gas furnaces and compatible Goodman/Amana models. The orifice threads into the manifold and precisely regulates the volume of natural gas injected into each in-shot burner. A drilled-out, clogged, or wrong-size orifice throws off the air-fuel ratio, producing lazy yellow flames, sooting, or under-firing — replacing it restores the correct BTU input and a crisp blue flame.
The OEM Goodman orifice is precision-drilled to the exact bore diameter your furnace's rating plate calls out for natural gas at the design manifold pressure. Generic or hand-drilled orifices change the firing rate and can create dangerous incomplete combustion. Never substitute an approximate size on a gas metering part — use the OEM spud.
Rated 2 of 5. Shut off gas and power, slide the burner off, and unscrew the old orifice from the manifold with a deep socket. Thread in the replacement snugly without over-torquing. About 10 minutes per orifice. Leak-check the manifold with soap solution before firing. Gas work should be verified by a licensed technician.
