The Honda 30520-ZDX-003 Ignition Coil (2) is a genuine OEM component designed for GX700 and GX800 horizontal shaft engines. As a direct Honda OEM part, this ignition coil is manufactured to the same specification as the original, ensuring the correct air gap, winding configuration, and trigger timing for these large-displacement engines. Honda supersedes ignition components at serial breaks, so confirm your engine serial number against the fitment table before ordering to make sure part number 30520-ZDX-003 is the correct coil for your unit.
Key Features
- Genuine OEM Ignition Output — wound and calibrated to Honda's original specification, delivering the correct spark energy and timing for GX700 and GX800 engines
- Direct OEM Replacement — designed to replace the original coil on GX700 and GX800 horizontal shaft engines with no re-gapping guesswork beyond the standard air-gap setup
- Serial Number Matters — Honda updates ignition coil part numbers at production serial breaks; always verify your engine serial number against the fitment table to confirm this is the right coil for your machine
- Restored Cold and Hot Starting — a weakened or failed ignition coil causes hard starting, misfires, or complete no-spark conditions; replacing it restores consistent spark across the full operating range
An ignition coil converts low-voltage battery or magneto current into the high-voltage pulse needed to fire the spark plug at the correct moment in the engine's combustion cycle. On the GX700 and GX800 engines, a coil that has degraded — whether from heat cycling, vibration fatigue, or internal winding failure — will produce a weak or absent spark, leading to rough running, misfires under load, or an engine that won't start at all. Replacing a worn coil with a genuine OEM unit like this one restores the precise spark energy these engines need to run cleanly and start reliably.
