{"product_id":"high-flow-air-filter-set-m157-m278","title":"High Flow Air Filter Set M157\/M278","description":"The Weistec Engineering High Flow Air Filter Set is engineered to enhance the performance of M157 and M278 engines. Through detailed analysis of the factory airbox, Weistec identified the filter's placement as a notable restriction. This high-flow air filter set addresses this by optimizing the filter's shape and position within the airbox, leading to significant improvements in airflow and power output across the entire engine power band.\n\nKey features of this air filter set include an increased flow area, optimized fitment within the factory airbox, and the amplification of performance when paired with a Weistec ECU Tune. The set includes two filters and is street legal in all US states. For optimal performance gains, Weistec recommends combining these filters with their ECU flash.\n\nThis high-flow air filter set is compatible with Mercedes-Benz models equipped with the 5.5 Biturbo and 4.7 Biturbo engines, specifically the M157 and M278 engine families. Applicable vehicles include the 2015-2020 Mercedes-Benz SL500 Roadster (R231) with the Twin Turbo 4.7L V8 (M278) engine.","brand":"Weistec Engineering","offers":[{"title":"Default Title","offer_id":52664119132472,"sku":"01-157-01039-7","price":251.1,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687540441.jpg?v=1784333548","url":"https:\/\/store.motormia.co\/products\/high-flow-air-filter-set-m157-m278","provider":"MOTORMIA","version":"1.0","type":"link"}
