With stock round air cleaner cover with front 'air scoop' intake","description":"High 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.   Note: See 905596 for the replacement air filter element.","brand":"K\u0026N","offers":[{"title":"Default Title","offer_id":47760310698328,"sku":"905232","price":314.87,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0142\/0777\/8870\/files\/905232k.jpg?v=1706681284","url":"https:\/\/roadsiderepairshop.com\/products\/k-n-twin-cam-rk-series-street-metal-o-s-air-cleaner-assy-16-17-softail-excl-16-17-flstfbs-14-16-touring-nu-with-stock-round-air-cleaner-cover-with-front-air-scoop-intake","provider":"Roadside Repair Shop","version":"1.0","type":"link"}
