This RDR performance ignition coil, spark plug wire, and boot upgrades the spark delivery on compatible GY6 and 139QMB engines for sharper throttle response and dependable ignition. Its tightly wound high-tension design reduces resistance and supports faster firing, with a 5–15% increase in spark output over stock coils. The cut-to-fit orange wire lets you build a tidy ignition setup without excess lead getting in the way.
Features
-
Stronger spark delivery: A 5–15% spark-output increase over stock coils supports consistent ignition on a compatible setup
-
Responsive performance: The tight-wound coil design reduces resistance and supports faster firing for improved throttle response
-
Custom wire routing: Trim the orange high-voltage lead to suit your vehicle rather than looping excess wire around the engine

Compare the original coil's ignition-system requirements, terminal arrangement, mounting points, wire routing, and spark plug connection before ordering. Engine code and two spade terminals alone do not establish compatibility.
Installation: Route the high-voltage wire clear of hot or moving components, leaving enough slack for normal movement. Cut the wire to the required length, then screw the supplied boot onto the wire end for a secure connection. Follow the vehicle's service procedure and confirm all ignition connections are secure before use.
