Air Cleaner Assy – 2013–2015 Softail\u003c\/h2\u003e\n\u003cp\u003eHigh Flow intake system. Re-use stock air cleaner cover for stock looks. Includes a special backplate; internal velocity stack; built-in breathers; oversized air filter element and hardware. A K\u0026amp;N Dyno test of this RK-series air cleaner assembly on a 2008 Street Bob showed an increase of 6.54 HP@5100 RPM; a 2014 103\" Ultra produced an additional 8.33 HP@4670RPM. The K\u0026amp;N RK-Series air cleaner assemblies are truly stealthy air cleaners since the stock air cleaner cover is re-used. Power increase is realized by replacing the stock filter and backplate. A special K\u0026amp;N powder coated aluminum backplate; with Dyno-tuned velocity stack; is required to house the oversized K\u0026amp;N air cleaner element. Built-in breathers replace the stock external breathers. Careful design made it possible to re-fit the stock air cleaner cover for a stock un-touched look.\u003c\/p\u003e\n\u003ch2\u003eFitment\u003c\/h2\u003e\n\u003cp\u003e13-15 Softail (NU)\u003c\/p\u003e\n\u003ch2\u003eProduct Details\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e K\u0026amp;N\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCategory:\u003c\/strong\u003e INTAKE \u0026gt; AIRCLEANER ASSEMBLIES\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUnit:\u003c\/strong\u003e 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct code:\u003c\/strong\u003e 904692\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"K\u0026N","offers":[{"title":"Default Title","offer_id":57361691148675,"sku":"MCS904692","price":118.7,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1329\/4265\/files\/904692k_c702a4a0-a3c2-400e-9656-6d0cb5d2aa15.jpg?v=1775212247","url":"https:\/\/hogparts.com\/products\/mcs904692","provider":"Hogparts UK Ltd","version":"1.0","type":"link"}
