NGK 6858 spark plug for the 2006-2015 Lexus IS250 V6 2.5L and other vehicles fires the spark that lights the fuel in each cylinder. Among NGK spark plugs, this one is meant for vehicles that already run DFE iridium alloy plugs.

• NGK Laser Iridium High Ignitability line
• Iridium alloy center electrode with a very high melting point, for modern high-efficiency engines
• Double fine electrode (DFE) with a platinum pin, for more complete fuel burn and smoother idle
• Platinum fine wire tip on the ground electrode for even wear in distributorless ignition systems
• Solid copper core, 98% pure copper, for heat dissipation and conductivity
• Trivalent metal plating for anti-corrosion and anti-seizing properties
