The genuine OEM Goodman 10716003 is a precision-drilled brass natural gas burner orifice (spud) for the Goodman/Amana AMV90704CXBA gas furnace and related models. The orifice meters the exact volume of natural gas into each burner, setting the flame size and BTU input. Because the drill size is matched to the furnace's rated input and manifold pressure, using the correct orifice is essential for clean combustion, proper flame color, and safe, efficient heating.
OEM 10716003 is drilled to Goodman's exact specification for this furnace's input rating. Generic or mis-sized orifices change the gas flow, producing an oversized flame (sooting, overheating) or undersized flame (poor heat, flame sensing faults). Never substitute an LP orifice or an unverified drill size — gas metering is safety-critical.
Requires removing the burner assembly, unthreading the old orifice, and torquing the new one to seal without cross-threading — 30–45 minutes. Shut off gas and power first, and leak-test all joints with soap solution after install. If you are not comfortable working on the gas train, have a licensed HVAC technician perform the replacement.
