⚡ AFTERMARKET IGNITION COIL SET | CARB RELIABILITY
Solve starting and running issues instantly. This aftermarket coil set provides a stronger, more consistent spark compared to aged OEM units, ensuring snappier throttle response and easier cold starts for your V-Twin.
- ✅ Snappier Throttle: Noticeable spark boost across the rev range.
- 🛠️ Easier Cold Starts: More reliable ignition when the weather turns chilly.
- ⚖️ Stable Idling: Helps maintain a consistent running engine.
- 📦 Set of Two: Includes both front & rear coils for a full upgrade.

Description
If your carbureted Hyosung is struggling with sluggish cold starts, unstable idling, or random running issues, the ignition coils are a prime suspect. The stock units fade over time due to heat and wear.
This Aftermarket Ignition Coil Set is a direct, reliable replacement designed to restore and improve spark strength and consistency across the entire rev range.
💎 Improved Reliability vs OEM
This aftermarket set provides a stronger and steadier spark compared to the standard coils, which is especially vital for maintaining performance for the carb based vtwins.
| Consistent Spark Reliable ignition for confident riding. |
Direct Swap Easy fitment, replaces OEM parts listed below. |
| Better Starts Snappier ignition helps engine turn over easier. |
Trusted Aftermarket Proven by many riders on the HyoRiders platform. |
📜 Confirmed Fitment (Carburettor Models ONLY):
These coils are designed as a direct replacement for the following carburettor models and **use a single spade connector**.
Reference OEM Part Numbers: 33410HK3101 | 33430HG5100 | 33410HG5100 | 33410HM8100 | 33410HG5800.

🔧 Installation Tips & Recommended Synergy Upgrades
Replacing coils is straightforward, but performance relies on the whole system. For the most reliable ignition possible, we highly recommend pairing this upgrade with the following:
- Easy Fit: Simply remove your old coils and swap them for these upgraded units.
- System Synergy (CRITICAL): The OEM black spark plug caps are often made from cheap plastic and are a primary cause of sparking issues as they age. They look like a coil failure but it’s the cap!
- NGK Caps: Upgrade to high-quality NGK Plug Caps for a permanent fix: [View NGK Plug Caps]

Life changing part of you are looking to change coils. I’ve put my new coils through a lot during the problematic idle and power problems. Works so well with the regulator you can purchase here. A total must have.

Absolutely amazing. Really perked the bike up. It has never felt so alive. And it’s so nice not having to use choke as now with these it just fires up and idles perfectly

Martin –
Just changed these on a GV125 and it starts and idles so much better. They make life much easier on cold mornings
eman ellul –
Just upgraded to these coils, the uprated regulator, the uprated stator and ngk caps with iridium spark plugs. I have to say it made an amazing difference, the bike almost no longer needs choke (less than a minute and only on first start in the morning), acceleration has improved significantly and my bike is now charging (which was my original problem :p). Very happy with all items 🙂
sverrema –
Ordered these from Norway. Fast delivery and fantastic support from the team. Bike start much easier and feels snappier in the throttle response. Fitted this together with NGK Caps and Iridium spark plugs.
