Restore your engine's firing consistency with the Blue Line Ignition Coil Assembly. An OEM-equivalent replacement for GY6 and 139QMB engine platforms, this coil solves common electrical issues like weak spark, intermittent stalling, and no-start conditions. The 18-inch lead provides extra flexibility for custom mounting and ensures compatibility with long-case scooters where the coil sits further from the cylinder head.
Fits 50cc, 125cc, 150cc, and 170cc 4-stroke engines. If your engine code includes "QM" or "FM", this is a direct fit:
Mechanic's Tip: Ignition coils often fail when hot, causing a scooter that runs for 10 minutes then dies. When installing this coil, always pair it with a fresh NGK CR7HSA spark plug � a fouled or old plug puts unnecessary strain on the new coil and can cause premature failure.
