The V-groove design ensures enhanced ignition, fuel efficiency, emissions reduction, and long-lasting performance. The V-groove center electrode design focuses the spark to improve combustion efficiency, the V-groove allows for a larger frame kernel, which improves the ignition process that leads to better starting performance, especially in cold conditions.
Advantages:
- V-Groove design improve combustion efficiency
- Lower ignition system voltage requirements
- Greater ignitability and performance over conventional spark plugs.
- "Trivalent Metal Plating" has superior anti-corrosion and anti-seizing properties.
- Increased fuel economy and lower emissions
