Part Spark Plugs Brand ?PHILTOP OEM Part Number DILFR6D11,AI5325 Center Electrode Core Material Copper Center Electrode Tip Material Iridium Ground Electrode Core Material Nickel Ground Electrode Tip Design Dual Fine Electrode - High Ignitability 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 1.043 in/26.50 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. PHILTOP double iridium spark plug made of great materials, its outstanding performance bring us back to strong power and fast starts. The plugs can reach 100000Mi service lifetime, is ideal for high performance engines. Compatibility Information 2007-2016 Sienna 2008-2016 Highlander 2007-2015 RX350 2007-2018 ES350 2005-2018 Avalon 2007-2017 Camry 2006-2012 RAV4 2009-2015 Venza 2010-2015 RX450h For more models, please match fitment to confirm! (Preset Gap: 1.1mm) A recommended is ignition coil and spark plug be replaced together to avoid common dysfunctions. Warm Tips: When installation, please use a torque wrench to tighten according to the specified torque. The groove ripple and the design of multiple umbrella ribs on the insulator effectively prevents flying foxes and surface flashover, providing pretty insulation performance. Iridium center electrode for better durability and more consistent and powerful spark, leading to better performance over lifetime of the spark plug. Iridium materials with outstanding performance of anti-high temperature and corrosion resistance, anti-high voltage and oxidation resistance ensures the spark plug long service life. Why choose PHILTOP spark plugs? Finer Center Electrode Double iridium material with high melting point refuse to accumulate carbon, and the side electrode technology will not wear the spark plug gap, extending its service life Higher Speed Start Requires less voltage and produces a strong spark for improved ignition performance and faster and easier starting. Less Fuel Consumption Iridium electrodes and proper gaps will improve the ignition curve, allowing fuel to burn more efficiently and reducing emissions. Smoother Driving Experience Accelerates more steadily and smoothly, rejecting jerks, jams and sharp jumps.
