Twin air ducts

synolimit

They make 2 of these as seen in the pics with the white car and the one members grey car. I personally like ones on the members grey car which are the rectangle ones origanally made for a 350z. These are just openings that stick back about 4 inches. How you place them, seal them, route them etc is all up to you. It's no difference than a brake duct cooling insert like shown on the member black car. You either hook up hose and route or don't.

You also don't cut the styrofoam. These mount higher where the stillen filters sit. The bumper beam is below.
