The best spark plugs for performance cars. Designed to endure a rough environment inside the combustion chamber and to maintain its stable ignition performance.
FEATURES
- 0.4 mm Iridium extra fine chip: For the electrode code, iridium alloy, which is superior to platinum alloy in heat resistance and durability. Therefore, it has a higher melting point and is used to produce an extra-fine chip of 0.4 mm.
- U-shaped grooved electrode: U-shaped grooved electrode delivers a stronger ignition spark and easily lights off both the weak and enriched mixture.
- Taper cut earth electrode: The taper-cut tip facilitates a smooth flow of air/ fuel mixture and prevents abnormal combustion inside the combustion chamber.
- Low voltage design excels in spark repercussion performance: Low voltage design enables spark repercussion even in low voltage and improves start-up ability.
