The Goodman B4089343 Burner Orifice (#43 drill) is the genuine OEM gas spud for the DDS80904BXA furnace and compatible Goodman/Amana models. Threaded into the manifold, this precision-drilled orifice meters the exact gas flow into each in-shot burner. The correct orifice size is critical for the right BTU input, clean combustion, and safe operation — a wrong or worn orifice causes over/under-firing, sooting, and rollout.

Specifications

Type: Threaded burner orifice / spud
Drill size: #43 (natural gas)
Function: Meters gas flow to a single in-shot burner
Fits model: Goodman DDS80904BXA and related furnaces
OEM part number: B4089343

OEM vs. Generic

The OEM Goodman orifice guarantees the factory-specified #43 bore and thread pitch, so BTU input matches the furnace rating plate exactly. Generic or mis-drilled orifices are a genuine safety and efficiency risk — even a fraction of a drill size changes the firing rate. Always match OEM for gas-metering components.

Installation Difficulty

Moderate (3/5) — Backs out of the manifold with a nut driver; verify #43 sizing for natural gas (LP conversions use a smaller orifice). Shut off gas, replace, then leak-check and confirm proper flame. Recommended for HVAC techs or confident DIYers; 20–30 minutes.
