NGK Iridium Spark Plug (FR6E1)

The fine wire center electrode on these NGK Laser Iridium spark plugs is made from an iridium alloy that has an extremely high melting point, making it durable and able to handle the demands of modern engines. These are actual OE or equivalent replacement spark plugs, designed to give you that same reliable performance and longevity you expect from your Mitsubishi Endeavor.

NGK uses a pure alumina silicate ceramic insulator for superior strength and better heat transfer, helping to prevent overheating. The trivalent metal plating on the plug body helps resist corrosion and seizing, making them easier to remove down the road. Most Laser Iridium plugs also feature a platinum pad on the ground electrode for even wear, especially in distributorless ignition systems. The copper core aids in heat removal, and triple seals are used to prevent leakage.
