Features

• Ruthenium Alloy Center Electrode reduces voltage requirement as well as ignition perfomance improvement and durability.
• Brass Terminal offers film fitting to plug wire or coil-pack.
• Plating coating for better insulation and excellent corrosion resistance.
• Outer electrode with platinum squre chip improves ignition, maximum durability, combustion speed and quality.
• The outer electrode has been shortened and engineered with the ideal shape to decrease weight for resistance against vibration

The tuning parts are also evolving with the appearance of spark plugs in consideration of fuel efficiency improvement and environmental performance.The use of spark plugs with an ignition position projecting 2 mm more than usual has been increasing. As you are aware, in sports vehicles such as the new Honda Civic Type R and Suzuki Swift Sport, this type of spark plug has also been adopted. We expect more and more cars will use this type of spark plug in the future.
