Part Spark Plugs Brand ?KAX OEM Part Number 1UNG18110, 99906910X9019, BY481ZFR5F, MZ602068,XP5224 Center Electrode Core Material Copper Center Electrode Tip Material Iridium Ground Electrode Core Material Nickel Ground Electrode Tip Design Taper Cut Ground Configuration Standard Ground Electrode Quantity 1 Electrical Terminal Type Non-Removable Nut Pre-Gap Size .044 in/1.118 mm Resistance 5000 Ohms Hex size 5/8 in/15.875 mm Insulator Height 50.50 mm Manufacturer Heat Range 5 Seat Type Flat Reach .75 in/19.05 mm Thread Diameter 14.00 mm [Faster Starts] The iridium spark plug enhances the center electrode design, concentrating spark energy and improving vehicle ignitability. It leads to smoother engine operation and eliminates misfire concerns. [Longer Lifespan] KAX automotive spark plugs feature iridium construction for durability and resistance to heat and corrosion. They effectively burn off carbon deposits, extending the plug's lifespan. [Fuel Economy] The 1.1mm fine wire iridium center wire tip design promotes optimal combustion and reduces carbon buildup. The external sealing gasket prevents gas leakage, enhancing fuel efficiency. [Trivalent metal coating] The spark plug offers high temperature durability and robust construction, with excellent resistance to corrosion and seizure, ensuring easy installation and disassembly. [Solid copper core] 98% pure copper core provides excellent heat dissipation, conductivity and ultra-wide thermal range. Features and Benefits Long lifespan The Double Iridium automotive replacement spark plug is engineered to last for up to 100,000 miles, double Iridium firing pin and ground electrode pin provide 4X longer service life. Faster Starts Iridium alloy needle shaped electrode, and the side electrode also adopts iridium alloy needle shaped electrode corresponding to it, maintaining high ignition resistance and best combustion performance Fuel Economy Fine wire iridium center wire tip design for sufficient combustion, efficiently reducing carbon accumulation. The external sealing gasket can prevent combustion gas leakage and relief fuel consumption. Superior Performance The mileage increases, starting is easier, horsepower significantly increases, engine idle speed improves, and overall performance is better. Installation Tips 1. Before removing the old spark plug, please clean the surrounding area to avoid dirt falling into the combustion chamber when the spark plug is taken out 2. Gentle action is required when removing the high-voltage wire connector, and avoid shaking the spark plug vigorously 3. Disassembled spark plugs one by one. 4. Do not skew when installing the spark plug.Please check the required gap specific for your application and gap each grounding electrode accordingly. 5. Use a torque wrench to tighten according to the specified torque. Don't use electric tools. 6. The spark plug should be kept clean, dry, and free of oil, otherwise it may cause faults such as electric leakage.
