BLUE LINE
Blue Line Ignition Coil 90° Cap, 18-Inch Lead - GY6 & 139QMB
Description
Make the most of limited space around your spark plug with this Blue Line ignition coil assembly for compatible GY6 and 139QMB four-stroke engines. Its 90-degree spark plug cap turns the lead away from the plug for easier routing in tight spaces, while the 18-inch lead gives you flexibility between the coil mounting point and cylinder head. It’s a practical replacement when a failed or weak coil is keeping you from riding.
Key Features
- 90-degree spark plug cap: Angled design helps route the lead where space above the plug is limited
- Complete assembly: Includes ignition coil, high-tension lead, and resistor-style spark plug cap
- 18-inch lead: Provides flexibility for routing to the spark plug
- Single mounting hole: One mounting eyelet secures the coil body
- Two spade terminals: Separate connection points for the ignition wiring

Match your existing coil’s mounting, electrical terminals, ignition-system requirements, and spark plug connection before ordering. Check that the angled cap clears the surrounding bodywork and engine components. An engine-code fragment such as “QM” or “FM” alone is not enough to establish fitment.
