{"product_id":"2-5l-iridium-spark-plugs","title":"2.5L Iridium Spark Plugs","description":"The COBB Subaru 2.5L Spark Plugs (D44700) are engineered for enhanced ignition performance in a wide range of Subaru vehicles, including WRX, STI, Legacy GT, and Forester XT models with the 2.5L engine. These are the same spark plugs factory-installed on the 2018 Subaru WRX STI Type RA and 2019 Subaru WRX STI, providing a reliable OEM-level component.\n\nConstructed with a durable laser-welded iridium-tipped center electrode and trivalent metal plating, these spark plugs are built to withstand demanding conditions. They feature a pre-set gap of .024 inches (0.6mm) and a heat range of 7, offering a one-step cooler temperature compared to some earlier factory plugs. This cooler heat range and tighter gap make them a suitable upgrade for modified turbocharged Subarus, helping to prevent pre-ignition and ensure smooth engine operation.\n\nThese spark plugs are sold as a set of four, ensuring you have all the necessary components for a complete engine tune-up. While they serve as a direct replacement for specific factory applications, they are also highlighted as a valuable upgrade for enthusiasts seeking to optimize their modified 2.5L turbocharged Subaru engines.","brand":"COBB","offers":[{"title":"Default Title","offer_id":52687428583736,"sku":"cobbD44700","price":65.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687893558.jpg?v=1784883963","url":"https:\/\/store.motormia.co\/products\/2-5l-iridium-spark-plugs","provider":"MOTORMIA","version":"1.0","type":"link"}
