K\u0026amp;amp;N intakes are designed to dramatically reduce intake restriction as they straighten air flow. This allows your Wrangler's engine to inhale a larger amount of air than the factory air filter assembly. More air means more usable power and acceleration throughout the engine's RPM range. The 57-1521 air intake comes with a chrome topped K\u0026amp;amp;N high-flow air filter and a heat shield that installs into the previous air box space. Air is directed through an aerodynamically engineered intake tube into the engine's throttle body for a guaranteed power gain. The tube accommodates the factory EVAP canister vent line and a replacement silicon crank case vent hose. The oversized air filter can be used for up to 100,000 miles before servicing is needed depending on driving conditions. This air intake is relatively easy to install usually in 90 minutes or less using the existing factory mounting points and requires commonly available tools. K\u0026amp;amp;N 57 Series FIPK's are street legal in all 50 US states and come with K\u0026amp;amp;N's Million Mile Limited Warranty. K\u0026amp;amp;N's easy to install air intake systems replace the restrictive factory air filter and air intake housing allowing for virtually unrestricted air flow. This power gaining air intake comes with K\u0026amp;amp;N's famous million mile limited warranty.\u003c\/span\u003e\u003c\/div\u003e\u003cbr\u003e\u003ctable cellspacing=\"10\" cellpadding=\"0\" align=\"left\" style=\"width:100%\"\u003e\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003e\n\u003cstrong\u003eAir Freight Prohibited:\u003c\/strong\u003e false\u003c\/td\u003e\n\u003ctd\u003e\n\u003cstrong\u003eNot Carb Approved:\u003c\/strong\u003e false\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\n\u003cstrong\u003eCarb Acknowledgement Required:\u003c\/strong\u003e false\u003c\/td\u003e\n\u003ctd\u003e\n\u003cstrong\u003eCarb Eo Number:\u003c\/strong\u003e D-269-22\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\n\u003cstrong\u003eLtl Freight Required:\u003c\/strong\u003e false\u003c\/td\u003e\n\u003ctd\u003e\n\u003cstrong\u003eProp 65:\u003c\/strong\u003e Y\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\n\u003cstrong\u003eEpa:\u003c\/strong\u003e N\/A\u003c\/td\u003e\n\u003ctd\u003e\n\u003cstrong\u003eClearance Item:\u003c\/strong\u003e f\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\n\u003cstrong\u003ePart Type:\u003c\/strong\u003e automotive\u003c\/td\u003e\n\u003ctd\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e K\u0026amp;N Engineering\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\n\u003cstrong\u003eManufacturer Part Number:\u003c\/strong\u003e 57-1521\u003c\/td\u003e\n\u003ctd\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\u003c\/table\u003e","brand":"K\u0026N Engineering","offers":[{"title":"Default Title","offer_id":43678207737969,"sku":"57-1521","price":367.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/2286\/3539\/files\/57_f76d6e05-1b11-4a35-b29e-8e707faf355d.jpg?v=1784651624","url":"https:\/\/541motorsports.com\/products\/k-n-57-1521-performance-air-intake-system-for-1991-1995-jeep-wrangler-4-0l-l6-yj","provider":"541 Motorsports","version":"1.0","type":"link"}
