Honda 30550-ZJ1-845 Ignition Coil Assembly (215MM) (Gray)

The Honda 30550-ZJ1-845 Ignition Coil Assembly (215MM) (Gray) is a genuine OEM component designed for GX610, GX620, and GX670 horizontal shaft engines, GXV610, GXV620, and GXV670 vertical shaft engines, and the EB11000 generator. As a direct Honda OEM replacement, this ignition coil assembly is manufactured to the exact specifications required for these engines, ensuring it integrates correctly without adaptation. Confirm your engine's serial number against the fitment table before ordering, as Honda periodically supersedes parts at serial-number breaks, and this coil assembly is size- and color-coded — (215MM) (Gray) — to a specific application within these engine families.

Key Features

• Genuine OEM Ignition Output — sourced directly from Honda, this coil assembly delivers the precise primary-to-secondary voltage transformation these engines require for consistent spark timing and clean combustion across the full operating range
• Size and Color Verified — the (215MM) (Gray) designation identifies this as a specific variant; match both the dimension and color to your existing coil before purchasing, particularly on twin-cylinder engines where two coils may differ
• Broad but Specific Fitment — covers GX610, GX620, and GX670 horizontal shaft engines; GXV610, GXV620, and GXV670 vertical shaft engines; and the EB11000 generator, including both single and twin configurations across these families
• Serial Number Awareness — Honda supersedes ignition components at defined serial breaks; verify your engine's serial number against the compatibility table to confirm this is the correct assembly for your unit

An ignition coil converts low-voltage current from the engine's charging circuit into the high-voltage pulse needed to fire the spark plug at the correct moment in the combustion cycle. On these larger-displacement Honda engines, a failed or weakened coil typically causes hard starting, misfiring under load, or a complete no-spark condition. Replacing a worn coil with the correct OEM assembly restores proper spark energy and timing, allowing the engine to start reliably and run at full power.
