These coils are for carby Hyosung bikes needing an improved sparking power through the rev range , which also helps in distance riding as sometimes the standard ignition coil does wane a lot due to fatigue. In winter the upgraded coils will actually help your bike start much sooner, so you are waiting less to warm and this also means it is recommended to use these upgraded coils with the NGK CAPS + LASER PLUGS also to take full advantage. Just search NGK on this website or browse the shop!

    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.

    Would recommend instant idle is better and easier starting and i have not noticed any bogging since installed well worth money

    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
