Description
HyoRiders has identified that the factory-fitted “China made” unbranded black HT leads/caps on the new 2024+ GV650 PRO ABS can sometimes fail, causing frustrating misfires or engine cutouts, especially on rainy days.
We offer this premium **NGK Upgrade HT Lead Spark Plug Caps (x2)** as a permanent, reliable fix.
These caps and integrated leads are the same trusted NGK quality you’d expect to find on high-end Japanese motorcycles.
⚡ Benefits of a Genuine NGK HT Caps Upgrade
We only use the full rubber NGK racing caps (not cheap plastic versions that crack) because they offer tangible performance advantages:
| ⚡ Faster Cold Starts | 🌡️ Runs Cooler | 🛠️ Vibration Resistant |
|---|---|---|
| Low resistance cables help spark earlier, waking up your plugs faster | Ceramic + phenolic resin + rugged rubber = heat-tolerant | Heat-pressed construction handles engine vibration well |
| 🛡️ Ceramic Resistor | ❄️ Weather Resistant | 🏁 Racing Grade Quality |
| Reduces electrical interference (essential for EFi bikes) | Rubber liners stop moisture leaks & prevent arcing | Rarely fails compared to OEM Golden caps |
✅ Confirmed Compatible Models (2024+ Models )
This kit fits the latest generation GV650 model names:
- **Hyosung GV650 PRO ABS** (EU Name / Global )
- **GV650PJ, GV650PC, GV650PA** (Asian Market Names)
🔧 Installation Notes & @Gabor’s Video Guide
The plug holes on the 650 V-twin are deep inside the rocker cover. It can be a fight to remove the old ones, but lifting the fuel tank provides easy access.
Check the product gallery! We have included Gabor’s full 3-minute installation video showing the old Golden caps being removed and the new NGK rubber caps installed. There is also a “Proof of Life” video showing the bike running smoothly afterward. See it below!
How to Install:
- Unscrew your old HT cap (↺ anti-clockwise).
- Screw in the new NGK HT Lead & Cap (↻ clockwise).
- Reuse your old dust cover to protect the coil from water/debris.⚠️
- Double-check before starting!
🛠️ *We recommend pairing these with our NGK Laser Iridium Spark Plugs for full performance!*
