Honda 30520-RRA-007 Plug Hole Coil

The Honda 30520-RRA-007 Plug Hole Coil is a genuine OEM ignition component designed for BF115, BF135, BF140, and BF150 outboard motors. As a direct Honda OEM part, it meets the exact electrical specifications Honda engineers built into these motors, ensuring the ignition system operates exactly as intended. Confirm your outboard's serial number against the fitment table before ordering, as Honda supersedes components at serial breaks within the same model line.

Key Features

• Genuine Honda OEM Ignition Output — built to the precise voltage and energy delivery specs required by BF115, BF135, BF140, and BF150 ignition systems, so the spark plug fires at the correct energy level on every stroke
• Direct Plug Hole Fitment — this coil seats directly into the plug hole on the cylinder head, replacing the original unit without rework or adaptation
• Serial Number Verification Recommended — Honda updates ignition components at production serial breaks; check your outboard's serial number against the compatibility table to confirm part number 30520-RRA-007 is correct for your unit
• Restores Clean, Consistent Spark — a worn or failing coil causes misfires, hard starts, and rough running under load; replacing it brings ignition performance back to spec and protects the cylinder from unburned fuel

A plug hole coil is a compact, individual ignition coil that mounts directly over a single spark plug inside its cylinder head well. It transforms low-voltage current from the engine's ignition control module into the high-voltage pulse needed to fire the spark plug reliably on each combustion cycle. When a plug hole coil degrades, the affected cylinder begins to misfire — symptoms include rough idling, a noticeable power loss at speed, increased fuel consumption, and difficulty starting — because combustion in that cylinder becomes inconsistent or fails entirely.
