The Honda 30500-Z0T-003 Ignition Coil Assembly (TEC) is a genuine OEM ignition coil built for GX120, GX160, and GX200 horizontal shaft engines, HS724 and HSS724 two-stage snow blowers, WB20, WB30, WH15, WH20, WMP20, and WT20 and WT30 water pumps, WDP20 and WDP30 diaphragm water pumps, and the FC600 tiller. As a direct Honda OEM component, this ignition coil assembly is manufactured to the same specification as the original part it replaces, ensuring the correct air gap, magnetic field strength, and output voltage for consistent spark delivery. Verify your unit's serial number against the fitment table before ordering, as Honda updates ignition components at specific serial breaks — part number 30500-Z0T-003 must match your machine's production range. This assembly suits a wide range of Honda-powered equipment, making it an essential stock item for service shops and field technicians.
Key Features
- Correct Spark Output — genuine Honda OEM construction ensures the coil delivers the precise high-voltage pulse the engine's ignition timing demands, with no misfires or hard-start conditions introduced by an incorrect coil specification.
- Broad Equipment Compatibility — a single coil assembly covering GX120, GX160, and GX200 horizontal shaft engines, HS724 and HSS724 two-stage snow blowers, multiple Honda water pump models, WDP20 and WDP30 diaphragm water pumps, and the FC600 tiller.
- Serial-Range Awareness — Honda supersedes ignition parts at production serial breaks; confirm your machine's serial number against the fitment table to ensure part number 30500-Z0T-003 is the correct coil for your specific unit.
- Drop-In OEM Replacement — this assembly installs using the original mounting points and air-gap specification, so no adaptation is needed when swapping a failed or weak coil.
The ignition coil assembly is the component responsible for converting battery or flywheel-generated voltage into the high-voltage spark that ignites the air-fuel mixture in the combustion chamber. Inside the coil, a primary winding builds a magnetic field as current flows through it; when the trigger signal interrupts that current, the field collapses rapidly across the secondary winding and produces the high-voltage pulse sent to the spark plug. When an ignition coil weakens or fails, the engine may crank without starting, misfire under load, or cut out unpredictably — symptoms that closely mimic fuel-delivery problems and are often misdiagnosed. Replacing a faulty coil with a correct OEM assembly restores reliable ignition across the full operating temperature range of the engine.
