NGK HT Lead & Cap for EFI Hyosungs? –  When it comes to spark plugs, we all know they are as important as the tyres themselves

Common Faulty HT Cap symptoms:

  • When engine is hot, the resistance changes (electrical woes)
  • EFI coils may misbehave if the HT leads are damaged.
  • The RPM needle can be bouncy (Coils & weak Caps commonly are hints)
  • Insulating material cracks after a while on some older Hyosungs.

📦  HT Lead & Cap specifications  ( from NGK )


Low Resistance Racing Cables improve sparking energy leading to improved engine performance; hence faster cold starts too since your coils will wake up your spark plugs sooner!


Superlative ceramic materials are incorporated that resist deterioration and have small
resistance variation under over-load, whilst the plug connector is made of sturdy phenolic resin, practically oblivious to tremendous heat and high tension, and very rugged rubber material.


The heat press insertion makes the construction all the more tough and vibration-resistant.


Helps to reduce electro magnetic interference and radio frequency interference, which can interfere with electronic ignition components, causing misfires and poor engine performance.


Special rubber liners on both ends prevent moisture from causing electrical leakage.


From a trusted brand. Rarely fails  unlike the “GOLDEN” branded caps on hyosungs that eventually show their weakness.

🚚    In Stock.     UK Delivery is 3-4 working days.
