This is a high quality reissue of the original Cobra intake that came as original equipment on the early Shelbys, made by Blue Thunder Products. A superior casting to the originals in every way, this manifold boasts a much improved port design for a significant power gain over the original piece. The perfect combination of increased performance with visual originality make this intake manifold a great choice. No more hassles with old castings that have outlived their useful days.
