NGK Laser Iridium High Ignitability spark plugs (DFE) are engineered to meet strict OE requirements for durability and ignition efficiency. These plugs feature a laser-welded iridium-tipped center electrode combined with a platinum disc or wire on the ground electrode. This Double Fine Electrode (DFE) design minimizes quenching and requires lower voltage to initiate a spark, ensuring reliable ignition even in high-compression or turbocharged environments. The 98 percent pure copper core effectively dissipates heat to prevent pre-ignition and overheating.

• Manufacturer Part Number: DILFR7K9G
• Electrode Material: Iridium-tipped center and platinum ground pad for even wear
• Insulator: Pure alumina silicate ceramic for superior strength and heat transfer
• Shell Plating: Trivalent metal plating provides anti-corrosion and anti-seizing protection
• Seal Integrity: Triple gasket seals prevent combustion gas leakage
• Quantity: Set of 4 spark plugs

These plugs are specifically recommended for vehicles originally equipped with DFE iridium alloy plugs to maintain factory performance and 100,000+ mile service intervals.
