The Goodman 10716005 is a genuine OEM natural gas burner orifice (spud) engineered for the Goodman VMES800805CXAA modulating gas furnace and compatible VMES-series models. Each orifice is precision drilled to a factory-calibrated diameter that meters the exact fuel volume your burners require, ensuring the correct BTU input, a clean blue flame, and safe, efficient combustion. A worn, corroded, or incorrectly sized orifice is a common cause of yellow flames, sooting, delayed ignition, and reduced heating output.
Genuine OEM orifices hold Goodman's exact drill tolerance, which off-brand spuds often miss. An oversized generic bore over-fires the burner (safety and efficiency risk); an undersized one starves it. For a combustion-critical component, OEM is the safe choice and preserves your warranty.
Install difficulty: Moderate. Requires shutting off the gas, removing the burner assembly, and swapping the orifice with a proper wrench. Combustion work should be verified by a licensed HVAC technician after installation.
