These louvers are custom designed to fit the rear openings of the Miata NA hood.  These mount on the bottom side of the hood for a clean look with minimal cutting of the underhood bracing.  Great for keeping those underhood temps and pressures down and keeping that turbo cool!

Made from aluminum and shipped flat as shown.  Use them as a template to mark out the opening on the hood before you form them to shape.  Easily formed and assembled by hand.

(the louvers installed at the front of the hood on the car in the photos are the GTM Gen II Hatch Louvers)
