Goodman B4089343 #43 Burner Orifice (Spud)

The Goodman B4089343 is a genuine OEM #43 drill-size burner orifice, or spud, for the Goodman ADS80453ANA gas furnace and compatible Goodman/Amana models. The orifice meters the precise volume of gas into each in-shot burner, setting the furnace's input rate and flame quality. A worn, enlarged, or incorrectly sized orifice causes over- or under-firing, sooting, and poor efficiency, so it should match the manufacturer's specification and fuel type exactly.

Specifications

Drill size: #43
Type: Threaded burner orifice / gas spud
Fuel: Natural gas (verify size against rating plate)
OEM part number: B4089343
Brand: Goodman (fits Amana-branded units)
Equipment: Gas furnace, model ADS80453ANA

OEM vs. Generic

The OEM B4089343 is drilled and gauged to the exact #43 bore your furnace was certified for, guaranteeing correct BTU input. Generic orifices can vary slightly in bore diameter, throwing off the firing rate and flame. With gas metering, that precision matters — always replace with the size specified for your unit and altitude.

Installation Difficulty

Moderate (3/5). Roughly 20–30 minutes; the orifice threads into the manifold and must be sealed and torqued correctly. Close the gas valve and shut off power first. Confirm there are no gas leaks after installation. Because this affects combustion, have the input rate and flame verified by a licensed HVAC professional.
