This cold side tube and single style max flow bridge is only applicable for aftermarket turbo options such as s300/s400 series chargers in the valley. Our precision cast CNC machined bridge section allows for maximum efficiency, as well as a perfect fit every time. The mandrel bent 3'' cold-side tube complements the y-bridge for the ultimate efficiency, flow, and maximum performance capabilities of your truck. This is a great kit for pullers, drag racers, and the do-it-yourself builders looking to assemble their own single turbo setup.
