Description
NGK Uprated HT Coil Spark Plug Cap / Covers – Hyosung GTR GT GV (Various Models)
( x2 Pieces )
NGK Spark Plug Cap for Hyosungs? Spark plugs are as important as the tyres themselves since we don’t go anywhere without either! Likewise, they are the hardest workers inside your engine from start to finish.
An HT Coil Spark Plug Cap plays a critical role as the middle-man between the actual spark plug and your ignition coil, to deliver a constantly good electrical flow (even when the bike is HOT)
Faulty HT Cap symptoms (this is why the OEM caps are NOT good):
- Bike jerks / surges when the HT Cap is HOTTER than usual
- Sometimes it will feel like there is a misfire between 6-9k revs
- The RPM needle can be bouncy/jerky
- Faulty/Damaged Caps -> Exhaust sounds can change (boggy)
- Insulating material cracks after a while on some older Hyosungs.

📦 NGK Upgrade HT Coil Spark Plug CAP cover Tech Specs
(Taken from NGK themselves):
- ⚡ FASTER COLD STARTS 🌡RUNS COLDER 🛠 VIBRATION RESISTANT
- ⚡ CERAMIC RESISTOR ❄ BETTER WEATHER RESISTANCE
- The NGK spark plug caps are designed to give perfect noise suppression across all frequencies whilst engine performance is not adversely affected whatsoever.
- Featuring a resistor element pressed in between the plug terminal and the high tension wire connection, the construction is extremely durable, the resistor element is long enough to prevent interior flashover, and steady resistance is maintained.
- 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. Special rubber liners on both ends prevent moisture from causing electrical leakage.

Fits a lot better than original plug cap and as always you can’t go wrong with NGK products. Very good quality plug cap.

Just upgraded to the uprated 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 🙂
