Increase performance and flow with our upgraded 3" Max Flow Bridge and Cold Side Kit. Our precision cast and CNC machined bridge section allows for maximum efficiency, as well as, a perfect fit every time. Our two-piece design allows for a much easier installation than the other kits on the market. Two M8 studs, 12-point nuts, and a high-strength O-ring locate and hold the 3" bridge together to eliminate the possibility of boost leaks. Our bridges have been pressure tested to over 100 PSI to ensure your truck can perform to its highest potential. The mandrel bent 3'' cold side tube complements the y-bridge for the ultimate efficiency, flow, and maximum performance capabilities of your truck. This cold side tube in combination with the max flow bridge is best suited for factory or drop in replacement chargers, as it resembles the factory intercooler routing.
