Most FIPK's are street legal in all 50 US states and come with a Million Mile Limited Warranty. K\u0026amp;N intake systems replace your vehicle's restrictive factory air filter and air intake housing. K\u0026amp;N intakes are designed to dramatically reduce intake restriction as they smooth and straighten air flow. This allows your vehicle's engine to inhale a larger volume of air than the OEM air filter assembly. More air means more usable power and acceleration throughout the engine's RPM range. The filters on these kits are washable and reusable. Most of our intake kits are relatively easy to install using tools commonly available\u003cbr\u003e\u003cbr\u003e    \u003cstrong\u003eFeatures:\u003c\/strong\u003e\u003cbr\u003e    * Adds up to 7.9 rwhp\u003cbr\u003e    * More airflow equals better acceleration and gains of up to 26 horsepower\u003cbr\u003e    * Engineered for your specific vehicle\u003cbr\u003e    * The K\u0026amp;N air filter is washable and reusable for life\u003cbr\u003e    * The cross-link nylon structure dissipates heat for cooler air temperature\u003cbr\u003e    * Easy installation is perfect for the do-it-yourselfer\u003cbr\u003e    * Your K\u0026amp;N Air Charger comes with an unlimited mileage, 1-year warranty against defective materials or workmanship\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003e57-2566 Product Specifications\u003c\/strong\u003e\u003cbr\u003eProduct Style: 57 Series FIPK\u003cbr\u003eEstimated Horsepower Gain: 7.54 HP @ 4996 RPM\u003cbr\u003eReplacement Filter: RF-1048\u003cbr\u003eCARB Exempt: Yes\u003cbr\u003eWeight: 8.8 lb (4 kg)\u003cbr\u003eProduct Box Length: 23 in (584 mm)\u003cbr\u003eProduct Box Width: 14.25 in (362 mm)\u003cbr\u003eProduct Box Height: 12.13 in (308 mm)\u003cbr\u003e","brand":"K\u0026N","offers":[{"title":"Default Title","offer_id":48337361338626,"sku":"KNN57-2566","price":317.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0787\/0618\/0354\/files\/57-2566_1_46851ad2-cb0a-49a6-ac76-1e6887e14c51.jpg?v=1787624331","url":"https:\/\/www.lethalperformance.com\/products\/k-n-05-09-ford-mustang-v6-4-0l-performance-intake-kit","provider":"Lethal Performance","version":"1.0","type":"link"}
