{"product_id":"ngk-high-performance-spark-plugs","title":"NGK High Performance Spark Plugs","description":"The NGK spark plugs are specialized ignition components designed as a direct-fit replacement for the Mercedes-Benz M156 and M159 engine families. By replacing the stock extended electrode design, these plugs mitigate the risk of pre-ignition often encountered during high-output operation, making them a recommended upgrade for vehicles equipped with Stage 2 or 3 supercharger packages.\n\nEach set includes 8 spark plugs that feature a colder heat range, specifically calibrated for improved performance and safety in supercharged engine configurations. These plugs are intended to enhance combustion efficiency and provide reliable ignition for engines producing over 630bhp. Please note that users must manually check and set the spark plug gap prior to installation to ensure proper engine performance.\n\nThis product is explicitly designated for use in specific Mercedes-Benz models with the M156 or M159 engines, such as the 2007 R63 AMG, and the 2008-2011 SL63 AMG Roadster (R230).","brand":"NGK \/","offers":[{"title":"Default Title","offer_id":52663100965176,"sku":"810089562272","price":56.12,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687077180.jpg?v=1784323820","url":"https:\/\/store.motormia.co\/products\/ngk-high-performance-spark-plugs","provider":"MOTORMIA","version":"1.0","type":"link"}
