Anyone got a carbon fiber air duct that goes on the front of the bumper also looking for a plenum spacer if so let me know thanks

 

Uploading the Forced Cold Air Induction Ram Air Duct picture. K&N element behind it retaining original air box. Yes it makes a difference and is easy to install. surface area permeability is greater with the filter element as opposed to a cone having NO direct permeability "the ability of a substance to penetrate or seep through a surface or material. It can be sealed & any type of charging motor in between. Will give your intake a little growl.
