Description
The standard “Yellow Box” spark plugs are fine for stock use, but a spirited Hyosung V-Twin deserves better. We cut through the hype and offer the proven performance upgrade: Genuine NGK Laser Iridium Platinum Plugs.
These aren’t just a gimmick; they are precision-engineered components designed for improved reliability vs the standard OEM units.
These are NOT the same as “IX Iridium (Yuck!)” , you want a “LASER IRIDIUM” plug for longevity and serious reliability!
💎 Improved Reliability vs OEM
NGK themselves provide the specifications that make these the best choice for longevity and performance:
| Laser-Welded Tip Iridium center electrode for durability. |
Platinum Ground Disc Massively extended lifespan over standard plugs. |
| Anti-Seizing Plating Trivalent metal plating for superior anti-corrosion. |
Consistent OEM Approved Design Reliable performance guaranteed. |
📜 Confirmed Fitment (V-Twin Models):
A pair of these plugs fits the following models as a direct replacement for Hyosung Part Number: 09482-00456
| GV125 / GT125 / R (All Years) | GV250 / GT250 / R (All Years) | GV650 / GT650 / R / S (All Years) |
🔧 Installation Tips
- **Engine Temp:** Ensure the engine is stone cold before removing or installing plugs to prevent thread damage to the cylinder head.
- **The Gap:** Do not adjust the gap, NGK Japan already gaps their spark plugs, so do not modify it , just fit and ride!
- **Anti-Seize:** A tiny smear of anti-seize compound on the threads prevents future seizing. The trivalent plating helps, but this is added insurance.
- **Torque Right:** Use a torque wrench (typically 18-22 Nm). Avoid over-tightening which can crack heads.

A great companion to the coils and caps. Highly recommended. Fast delivery to Spain. Excellent service from Marcel

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 🙂
Bike is a 2003 gv250 carby model

Installed on RC 2018. The crem de la crem of spark plugs. Engine smooth, power on demand has improved, acceleration unbelievable and a clean start. Worth the money, combine with the NGK caps for optimum performance.
