💎 IGNITION COIL PACK | EFI PERFORMANCE UPGRADE

Eliminate misfires and restore lost power. If your Hyosung struggles to start or stutters under load, your factory coil is likely failing. This high-output replacement is designed specifically for Delphi EFi systems to provide a consistent, high-voltage spark for a smoother ride.

✅ Stronger Spark: Fixes hard starting and “weak” engine feel.
🛠️ Direct Replacement: Built for Delphi ECU-equipped Hyosung models.
⚙️ OEM Quality: Meets or exceeds factory 33410H98A00 specs.
📦 What’s Included: 1x Ignition Coil (Sold individually).

⚠️ SYSTEM CHECK: This coil is for Delphi ECU models only (typically 2013+ onwards).
❌ It will NOT fit older bikes using Sentec, Daewoo, or Mitsubishi electronics.

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.

Quality internal windings designed to survive the heat of a high-performance engine.

Consistent Firing Prevents “hesitation” at high RPMs.	Weather Sealed Improved casing to resist moisture shorts.

🔧 Install & Care Tips

Check your Quantity: V-Twin models (GT/GV/ST7) require two coils. Singles (GD series) only require one.
Dielectric Grease: Apply a small amount to the coil terminals to prevent corrosion and ensure maximum conductivity.
HT Lead Check: This coil does not include the wire. Ensure your existing HT lead is not cracked; a leaking wire will kill a new coil quickly!
