The Goodman 10716003 is a genuine OEM natural gas burner orifice (spud) for the GKS91155DXAG gas furnace and compatible Goodman/Amana models. Precision-drilled from solid brass, the orifice meters the exact volume of natural gas delivered to each burner, setting the flame size and BTU input for clean, efficient combustion. Using the correct orifice is essential — an oversized or damaged spud causes sooting, delayed ignition, and unsafe over-firing, while an undersized one starves the burner.
OEM 10716003 is drilled to Goodman's exact orifice size for this furnace's input rating and manifold pressure. Generic or hand-drilled orifices can throw off the gas/air mix, producing yellow flames, carbon monoxide, and efficiency loss. For a combustion-critical component, only the OEM-spec orifice is recommended.
Moderate (3/5). About 15–20 minutes for an experienced tech: shut off gas and power, remove the burner assembly or manifold as needed, unscrew the old spud with the correct wrench, thread in the new orifice snugly (do not over-torque brass), and reassemble. Verify flame appearance and check for gas leaks with a bubble solution afterward.
Compatibility note: Confirm this is a natural-gas application and match the original part number before ordering. Fits Goodman GKS91155DXAG.
