{"product_id":"m156-row-airbox-set-2","title":"M156 ROW Airbox Set","description":"The Weistec M156 ROW Airbox Set directly replaces the restrictive US Spec M156 engine's mass air flow sensor housing with a higher-flowing profile found in ROW (Rest of the World) airboxes. It is particularly beneficial for vehicles equipped with Stage 1 or Stage 2 M156 Supercharger Systems, and it is a requirement for Stage 3 systems. The set includes both left and right airboxes and brand new mass air flow sensors. For optimal performance, Weistec recommends combining these airboxes with their M156 ECU Upgrade and M156 High Flow Air Filters.\n\nKey features of this airbox set include an increase in horsepower by 5-10 HP, an increased flow area, and amplification of performance for Weistec Supercharger or ECU Tunes. The set comes as a pair and includes new MAF sensors.\n\nThis product is not legal for sale or use on pollution-controlled motor vehicles in the United States. It is specifically designed for the M156 engine family, with confirmed fitment for Mercedes-Benz models including the 2007-2011 SL63 AMG Roadster (R230), 2007 Mercedes-Benz R63 AMG Base (W251), and 2011 Mercedes-Benz ML63 AMG Base (W164).","brand":"Weistec","offers":[{"title":"Default Title","offer_id":52866625765688,"sku":"01-156-00743-7","price":549.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687410816.jpg?v=1787909386","url":"https:\/\/store.motormia.co\/products\/m156-row-airbox-set-2","provider":"MOTORMIA","version":"1.0","type":"link"}
