Description
Ignition coils live a hard life, constantly exposed to engine heat and road vibration. Over time, internal break-downs lead to a weak spark, causing poor fuel economy and frustrating misfires. This coil is the definitive fix for the modern Hyosung EFi range. Whether you are daily commuting or out for a weekend blast, ensure your ignition system has the punch it needs to perform.

Confirmed Matches: Fits GD250R, GD250N, GT250R EFi, GT650R EFi, GV650 EFi, and ST7 (GV700i) models from 2013 to 2020. Also matches GV250 EFi models strictly between 2016 and 2018.
This aftermarket version will not fit any carburettor models or early fuel-injected bikes using Sentec, Daewoo, or Mitsubishi ECU electronics.
Factory spark plug caps are notorious for failing under thermal stress. Pair this coil with **NGK Performance Caps & Iridium Plugs** for the ultimate secondary ignition reliability. Get the NGK Upgrade kit here.
🔧 Install & Care Tips
- Check your Quantity: V-Twin models (GT, GV, and ST7 series) require two coils to complete a full refresh. Single-cylinder models (GD series) only require one.
- Dielectric Grease: Apply a small dab to the primary terminal pins to seal out air, prevent moisture corrosion, and maintain maximum conductivity.
- HT Lead Check: This coil block does not include the high-tension lead wire. Ensure your existing HT lead is free from cracks; a leaking wire will cause secondary tracking and damage a new coil quickly.
If you want to verify your primary resistance readings or need the factory pinouts for a Delphi wiring harness, or For diagnostic manuals, wiring schematics, or advice , head to the forums.
