Center Electrode Core Material Copper Center Electrode Tip Material Iridium Ground Electrode Core Material Nickel Ground Electrode Tip Design Standard 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 6 Seat Type Flat Reach .75 in/19.05 mm Thread Diameter 14.00 mm [Faster Starts] The double 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] PHILTOP automotive spark plugs feature double 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. Please confirm that the spark plug fits your vehicle (Year+Make+Model+Engine Size) before buying! Make sure that the ignition gap is correctly selected before purchasing! A recommended is ignition coil and spark plug be replaced together to avoid common dysfunctions!

(Preset Gap: 1.1mm) Why Choose PHILTOP Double Iridium Spark Plug? Reduce Carbon Formation The iridium metal electrode and the appropriate ignition gap increase the charge accumulation effect, improve the ignition path, and make the fuel mixture burn more fully, thereby reducing carbon deposition Rapid Ignition Sophisticated electrode design provides more excellent and reliable ignition performance for the car, higher ignition efficiency, faster start-up of the car, and more stable and smooth acceleration Improved Fuel Economy Iridium metal electrodes better increase combustion efficiency, enhance vehicle power performance better, better save fuel consumption, be economical Avoid Abnormal Shaking The acceleration is smoother, the idle speed is more stable, and the engine vibration caused by the oxidation of the spark plug is effectively solved so that there is a better driving experience 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, so as not to damage the performance of the spark plug 3. Disassembled spark plugs one by one. 4. Do not skew when installing the spark plug. 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.
