The Goodman 10716003 Natural Gas Orifice is a genuine OEM burner spud for the GMV950453BXBA two-stage variable-speed gas furnace. Each orifice is precision-drilled to meter the exact natural-gas flow required for clean, efficient combustion and correct BTU input across the burner array.
OEM vs. Generic: Orifice drill size directly controls firing rate and flame quality. The OEM 10716003 guarantees the factory-specified bore, protecting against sooting, delayed ignition, and CO risk. Generic orifices with off-spec bores can under- or over-fire the furnace — never worth the gamble on a combustion component.
Install difficulty: Moderate (2/5). Shut off gas and power, remove the manifold, thread out the old orifice, and install the new one to spec. Requires basic combustion knowledge; verify manifold pressure after replacement. Recommended for experienced DIYers or a licensed technician.
