The 0163F00018 is a genuine Goodman/Amana natural gas burner orifice (spud) engineered for the AMH81405DXCF gas furnace and other compatible Goodman multi-position models. This precision-drilled orifice meters the exact gas flow to each in-shot burner, ensuring the correct BTU input, clean ignition, and safe, efficient combustion. A worn, corroded, or incorrectly sized orifice causes weak flames, delayed ignition, sooting, and lockouts — replacing it with the factory-spec part restores rated performance.
Our OEM Goodman orifice is drilled to the manufacturer's exact bore diameter for your model's rated input. Generic or aftermarket orifices often vary in bore size, which can under- or over-fire the furnace and trip safety limits. For a gas-metering component, OEM accuracy is strongly recommended.
Moderate — requires shutting off gas and power, removing the burner assembly, and threading the orifice to spec. A wrench and basic furnace service experience are needed. If you are not comfortable working on gas components, use a licensed HVAC technician.
