Hi, this auction is for a pair of custom cut steel SAPPHIRE COSWORTH style bonnet vent appetures, it also includes a set of 8 lugs for mounting purposes. These are cut from the same grade and thickness steel as most car panels, they can be welded into any steel bonnet from many different car manufacturers. This allows for the mounting of SAPPHIRE COSWORTH BONNET vents into car models other than sapphire cosworth. Any competent bodyshop should be able to tack weld these into a bonnet then finish them off seamlessly. The opening in the appetures is a snug fit so as to give the same appearance as the OEM ones would. They have been CNC cut using the latest hydrojet water cutting technique under ISO9001 (quality) and IS014001 (environmental) accreditations. These are a quality UK made item from quality materials. I will ship these worldwide.
