Perfecto para Softail Deluxe '17 Intrucciones claras sobre como instalar, tener en cuenta que al modificar sobre un filtro stock, puede necesitar remapeo la moto Tambien recomiendo buscar el rain sock de la marca filter wears, ya que el que recomienda amazon para esta publicacion le quedo corto

I replaced an Arlene Ness Big Sucker with this K&N and it was worth every dime. Way more air flow and a significantly noticeable increase in power. Instructions were a little vague but it wasn't that hard to figure out. Looks good and it gives the desired effect.

Ive tried a few different breathers on my 2015 Harley Road glide and when this was on sale i had to try it. Install was straight forward with clear included instructions. Parts are quality made and thought went into engineering this to fit perfect. Fit touring Harleys really well. This is my favorite to date. Included pictures. Kit comes with a K&N decal and a emission decal/ tag if needed for your state Inspection. Highly recommended.
