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.
Key Features
- Complete assembly — includes 2-pole coil, 18" spark plug wire, and 90-degree resistor-style spark plug cap
- 18" plug wire — extra length for custom mounting and long-case engine compatibility
- Weather-sealed cap — thick rubber boot prevents moisture and debris from grounding out your spark
- Dual-pole connection — plug-and-play fit for standard GY6 wiring harnesses; no splicing required
- Wire Length: 18 inches (457mm)
- Coil Type: 2-pole (primary/ground)
- Spark Plug Cap: 90-degree resistor style
- SKU: 0900-1104

| Engine Type | Compatible Engine Codes |
|---|---|
| 50cc 4-stroke | 139QMB, 1P39QMB, 139QMA, YN139QMB |
| 125cc / 150cc | 152QMI, 157QMJ, 1P57QMJ, JJ157QMJ, BN157QMJ, YN1P57QMJ, 1P52FMI, 154FMI |
| 170cc / Stroker | 161QMK, 1P61QMK, BN161QMK-A |
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.
