Classic Pair of 4" Angled Aluminum louvered panels for your project. Louvers are made on a high tonage press brake for much crisper stronger forms. This is much easier and less expensive than having your fender, hood, panel or firewall removed and taken to the bodyshop and louvered. Just trim this panel to fit your and weld epoxy or rivet in place. These are made from .050" thk Aluminum. The louvers are 4 1/32" wide and 3/8 tall. The outer dimensions are 7" x 16" for each panel.
