Iridium Pro Spark Plugs 14x19x16mm Heat Range 9 APR

Part #: Z1003101

APR Iridium Pro Spark Plugs are the excellent upgrade for tuned engines. Our spark plugs are made from Iridium, which is one of the strongest materials you can use in this type of application.They run cooler, resist preignition, last longer than other materials with higher melting points, and even require less voltage to produce a strong spark. The electrode is harder and stronger than other materials and with its copper core can dissipate heat more easily, is better protected from melting, cracking, and other limitations found with standard plugs.These plugs were designed for use on tuned and higher output vehicles that benefit from a plug cooler than the factory heat range. They are great for high boost, high cylinder pressure, high cylinder temperatures, and high power situations, and they pair nicely with a set of APR ignition coils, where applicable.Heat range 9 spark plug (Similar: Bosch 3, Brisk 10, Denso 27, and NGK 9)152 percent higher melting point than silver, 125 percent higher than copper, and 38 percent higher than platinum.Stronger than copper and platinumDesigned for high performance / tuned vehicle applicationsProjected insulator designLower Required supplied voltageCooler operating temperature than stock plugsOptimized electrode design for hard to ignite fuels, such as ethanolResists preignition better than stock plugsPerfect for upgraded APR vehiclesAn excellent match for APR ignition coilsThread reach: 19mmThread diameter: 14mmHexagon: 16mmSeat Type: GasketInstall Torque: 25 NmMade in the EUDetails:Center Electrode Tip Material: IridiumEmission Code: 6Grade Type: PerformanceIndexed: NoInsulator Material: CeramicProduct Type: Ignition Systems (Spark Plugs)
