Description
The standard factory spark plugs get you from A to B, but if you want to unlock the cleanest, most efficient combustion inside your GV300S engine, this high-grade spark plug kit is the ideal choice. The NGK Laser Iridium range is built for excellent longevity and rock-solid spark delivery. By using a platinum-tipped ground electrode and a super-fine iridium center point, they give your motor maximum firing power. This results in sharper throttle response, better fuel economy, and absolute peace of mind on everyday roads.

📜 Confirmed Fitment Guide
Modern Liquid-Cooled 300cc V-Twin: Direct fitment for the modern fuel-injected bobber engine lines detailed below.
- Hyosung GV300S Aquila Bobber EFi: Fits all standard models from 2020 onwards.
- Hyosung GV300SS Aquila Spoke: Fits all wire-wheel variations.
- Hyosung GV300R Street Naked: Fits all modern street-focused versions.
- Older Generation 125 / 250 / 650 Models: Sized specifically for modern 300cc engine head clearances. It will not fit classic air-cooled bikes like the GV125, GV250, or old GT sport models.
🔧 Install Tips
- Do Not Gap: These come pre-gapped by NGK Japan for the 300cc engine setup (approx 0.8-0.9mm). Trying to adjust the gap spacing yourself can easily snap or chip the very delicate iridium center needle tip. Install them dry right out of the box.
- Torque Down Carefully: Always use a proper torque wrench on spark plugs. Overtightening can snap the metal threads inside your engine block or crack the outer ceramic casing. Make sure to only install them when the engine is completely cold.
- Read Your Old Plugs: Your old spark plugs act like a small diagnostic window into your top end. Take note of their firing tips—if they are powdery white the motor is running lean, and if they are black or wet with engine oil, you may have a worn seal leaking into the cylinder.
- Manufacturer Reference Cross-Match: Directly replaces original production factory record number 09482-00456.
