3" Genuine BlingLights Flex hose expands to 36" in length.  They are universal, very durable and great for custom applications like  Cold Air intake Ducting or Brake Ducting. Has "memory" flex and will  hold its shape, so it can be used to get air from your lower valance into  your filter, or cool your brake rotors on track days. It is made of a high grade flexible plastic with a wire core to hold its shape. Hose has 3" ID so  it will slip over 3" pipes without requiring a coupler like some off the  shelf hoses. This product is made for us in Japan and has a higher heat tolerance than generic equivalents we have tested.
 
 These are cut into 3ft sections fully expanded and will compress to an  11" size, very easy to trim with tin snips, scissors or wire cutters.  Will leave clean edges when cut with snips.
