They come with K\u0026amp;N's No-Hassle Lifetime Limited Warranty. These intake kits use only non-metallic rotationally molded tubes that can reduce air temperature and decrease intake sound over a metal tube. Restriction can exist BETWEEN an air filter and the engine reducing the benefit of a K\u0026amp;N Air Filter alone. The weakest link in the airflow chain robs a vehicle of its natural horsepower. Often that weak point is the factory air path leading to the engine. K\u0026amp;N Air Intake Kits virtually eliminate air path restriction by replacing the air filter and the entire air path to the engine. The aerodynamically engineered tube drives a massive amount of air into an engine, which translates into POWER. 57i Intakes are not legal for use in California and other US States adopting California emission standards.\u003cbr\u003e\u003ca href=\"https:\/\/d32vzsop7y1h3k.cloudfront.net\/da906bbbfc74a5a6d19c9f5df6963c22.PDF\"\u003eInstallation Instructions\u003c\/a\u003e\u003cbr\u003e","brand":"K\u0026N Engineering","offers":[{"title":"Default Title","offer_id":50646131343524,"sku":"KNN57I-1000","price":367.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0555\/1859\/3188\/files\/e100c9ef0f8706c365ad100f75cb3c5aL.jpg?v=1735930191","url":"https:\/\/www.4x4outfitter.com\/products\/k-n-98-05-bmw-3-series-generation-ii-induction-kit","provider":"4x4Outfitter","version":"1.0","type":"link"}
