{"product_id":"57i-series-performance-air-intake-system","title":"57i Series Performance Air Intake System","description":"The K\u0026amp;N 57i Series FIPK Cold Air Intake is engineered to free your vehicle from the restrictive size of the factory air box, designed to enhance performance across the entire RPM range. This induction kit replaces the entire factory air intake system, offering improved throttle response and engine sound.\n\nThe system features a large, oiled cotton air filter with a high-flow design, providing more airflow at lower restriction than a standard OE replacement filter. Its increased surface area allows it to capture and hold more dirt, extending its service life up to 100,000 miles before cleaning is needed. This air intake system requires no tune for installation.\n\nThis K\u0026amp;N 57i Series induction kit is specifically designed for the 2002-2007 Subaru Impreza WRX and 2004-2007 Subaru Impreza STi AWD models. It is important to note that this intake system is not legal for use in California and other US states that adopt California emission standards.\n\nAir intake systems are a popular first modification for enhancing engine bay aesthetics, improving engine sound, and boosting vehicle performance. K\u0026amp;N has been a leader in filtration technology for over 50 years, offering products designed to increase performance, protection, and longevity.","brand":"K\u0026N","offers":[{"title":"Default Title","offer_id":52686491615544,"sku":"57-0626","price":212.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687879981.webp?v=1784874356","url":"https:\/\/store.motormia.co\/products\/57i-series-performance-air-intake-system","provider":"MOTORMIA","version":"1.0","type":"link"}
