Upgrade your GY6 or QMB139 ignition system with this RDR high-tension performance ignition coil. The tightly wound coil design reduces current resistance and increases firing speed, delivering a stronger, more consistent spark for improved throttle response and reliability. The orange high-voltage wire and spark plug boot are left unattached from the factory — allowing you to cut the wire to your exact routing length before screwing on the boot.
Installation Note: The coil wire is left unattached to the spark plug boot to allow for custom-length fitment. Cut the wire to length, then screw the boot onto the wire end.
