{"product_id":"m156-row-airbox-set-1","title":"M156 ROW Airbox Set","description":"The Weistec M156 ROW Airbox Set directly replaces the restrictive US Spec mass air flow sensor housing found on factory M156 engines. By utilizing a higher-flowing profile, common in \"Rest of the World\" (ROW) airboxes, this system allows the engine to breathe more freely.\n\nUpon installation, users can expect a noticeable improvement in engine sound, with a more aggressive note. The improved airflow also contributes to better throttle response and an enhanced power band, with an added 5-10 horsepower. This set includes both left and right airboxes and comes with brand new mass air flow sensors. For optimal performance, Weistec recommends combining this kit with their M156 ECU Upgrade and High Flow Air Filters. Vehicles equipped with Stage 1 or Stage 2 M156 Supercharger Systems will significantly benefit from the increased flow, while it is a mandatory requirement for Stage 3 systems.\n\nThis product is not legal for sale or use on pollution-controlled motor vehicles. It is specifically designed for the Mercedes-Benz M156 engine family. The vehicle application includes: 2011-2008 Mercedes-Benz SL63 AMG Roadster (R230), 2007 Mercedes-Benz R63 AMG Base (W251), and 2011 Mercedes-Benz ML63 AMG Base (W164), all equipped with the NA 6.2L V8 (M156) engine.","brand":"Mercedes-Benz","offers":[{"title":"Default Title","offer_id":52689057841464,"sku":"810089562258","price":704.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687380737.jpg?v=1784900973","url":"https:\/\/store.motormia.co\/products\/m156-row-airbox-set-1","provider":"MOTORMIA","version":"1.0","type":"link"}
