{"product_id":"z1003100","title":"APR Iridium Pro Spark Plugs - 14x26.5x16mm - Heat Range 9","description":"\u003cp\u003eAPR 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.\u003cbr\u003e\nHeat range 9 spark plug (Similar: Bosch 3, Brisk 10, Denso 27, and NGK 9)\u003cbr\u003e\n152% higher melting point than silver, 125% higher than copper, and 38% higher than platinum.\u003cbr\u003e\nStronger than copper and platinum\u003cbr\u003e\nDesigned for high performance \/ tuned vehicle applications\u003cbr\u003e\nNon-projected insulator design\u003cbr\u003e\nLower required supplied voltage\u003cbr\u003e\nCooler operating temperature than stock plugs\u003cbr\u003e\nOptimized electrode design for hard to ignite fuels, such as ethanol\u003cbr\u003e\nResists preignition better than stock plugs\u003cbr\u003e\nPerfect for upgraded APR vehicles\u003cbr\u003e\nAn excellent match for APR ignition coils\u003cbr\u003e\nThread reach: 26.5mm\u003cbr\u003e\nThread diameter: 14mm\u003cbr\u003e\nHexagon: 16mm\u003cbr\u003e\nSeat Type: Gasket\u003cbr\u003e\nInstall Torque: 25 Nm\u003cbr\u003e\nMade in the EU\u003c\/p\u003e","brand":"APR","offers":[{"title":"Default Title","offer_id":47093010006320,"sku":"Z1003100","price":35.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0677\/7582\/4176\/files\/d340d678f6394f7b607e7f40e1ee94e6.jpg?v=1750125144","url":"https:\/\/es-performance.com\/en-us\/products\/z1003100","provider":"Eurosport Performance","version":"1.0","type":"link"}
