{"product_id":"performance-air-intake-system-24","title":"Performance Air Intake System","description":"The K\u0026amp;N 57i Series Generation II performance air intake system is engineered to boost your BMW's performance by increasing airflow to the engine.\n\nThis intake system pairs a roto-molded HDPE tube with an oversized, conical oiled cotton air filter. The K\u0026amp;N High-Flow Air Filter™ provides exceptional filtration and requires cleaning only every 100,000 miles under normal highway driving conditions. A custom heat shield is included to help insulate the intake air from the high temperatures within the engine bay, ensuring optimal performance.\n\nDesigned as a direct replacement for the factory air filter and intake tube, the K\u0026amp;N 57-0691 typically installs in 60 minutes or less using simple hand tools. This system is compatible with 2011-2017 BMW 520i and 528i models. Some K\u0026amp;N intakes are not legal for sale or use on pollution-controlled motor vehicles in California; always check specific product specifications for CARB status for your vehicle.\n\nThe K\u0026amp;N 57-0691 comes with K\u0026amp;N's No-Hassle Lifetime Limited Warranty.","brand":"K\u0026N","offers":[{"title":"Default Title","offer_id":52686497513784,"sku":"57-0691","price":212.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687880516.webp?v=1784874395","url":"https:\/\/store.motormia.co\/products\/performance-air-intake-system-24","provider":"MOTORMIA","version":"1.0","type":"link"}
