{"product_id":"silver-racing-spark-plug-4","title":"Silver Racing Spark Plug","description":"The Brisk Silver Racing 2MOR10S spark plug is designed for performance applications, featuring a 12mm thread size with a 1.05\" (26.1mm) reach and a 14mm Bi-Hex dimension for secure fitment. It incorporates a gasket seat for optimal sealing and a non-projection tip, complemented by a silver center electrode and a cut-back ground electrode for enhanced performance.\n\nIt is noted as being one heat range colder than the NGK 97506 SILZKBR8D8S, making it a suitable replacement for applications requiring a cooler plug. The Brisk Silver Racing 2MOR10S is a direct replacement for the NGK SILZKBR9F8S (BMW# 12120042724).\n\nPopular applications for this spark plug include the BMW 335i, BMW Mini Cooper S, Mercedes Benz C63 AMG, and Smart ForTwo 1.0L 3 Cylinder. For certain BMW applications such as N54\/N55, S54\/S55\/S63 engines, and specific Audi models like the B9 S4, S5, RS5, and SQ5 powered by the EA839 engine, these plugs are recommended as performance upgrades. Note that some users suggest verifying the plug gap before installation, as they may not come pre-gapped, with a recommended range typically between .020-.025 inches.","brand":"Brisk","offers":[{"title":"Default Title","offer_id":52687273623864,"sku":"2MOR10S","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687891869.webp?v=1784882091","url":"https:\/\/store.motormia.co\/products\/silver-racing-spark-plug-4","provider":"MOTORMIA","version":"1.0","type":"link"}
