This upgrade improves airflow, enhances performance, and cleans up your engine bay with a bold, functional design.\u003c\/p\u003e\n\u003ch3\u003eWhy Choose the HSP Max Flow Bridge and Cold Side Tube?\u003c\/h3\u003e\n\u003cp\u003eThe factory bridge and cold side pipe on the LLY are known weak points. They are restrictive and poorly designed for airflow, with inefficient bends that limit performance. The factory bridge, in particular, is a major source of power loss and boost leaks.\u003c\/p\u003e\n\u003ch3\u003eWhat Makes the HSP Max Flow Bridge and Cold Side Tube Different?\u003c\/h3\u003e\n\u003cp\u003eBoth the bridge and cold side tube are upgraded to a 3\" diameter, providing a significant improvement in airflow. The Max Flow Bridge is precision-cast aluminum, CNC machined for optimal internal flow and strength. Its pressure-tested to over 100 PSI and secured using two M8 studs, 12-point nuts, and a high-strength O-ring to eliminate the risk of boost leaks.\u003c\/p\u003e\n\u003cp\u003eThe Cold Side Tube also features a 3\" mandrel-bent design, creating sweeping bends that reduce turbulence and increase efficiency. This setup pairs best with factory or drop-in replacement turbochargers, as it maintains OEM-style intercooler routing.\u003c\/p\u003e\n\u003ch3\u003eWhats Included\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e1x Bridge Neck (HSP-IN-209)\u003c\/li\u003e\n\u003cli\u003e1x Bridge (HSP-IN-222)\u003c\/li\u003e\n\u003cli\u003e1x Coldside Tube (HSP-IN-213)\u003c\/li\u003e\n\u003cli\u003e1x Bridge Neck O-Ring (RFB-670-RFAB)\u003c\/li\u003e\n\u003cli\u003e1x 1\/8'' NPT Brass Plug (RFB-811-RFAB)\u003c\/li\u003e\n\u003cli\u003e2x Bridge Neck Stud (RFB-902-RFAB)\u003c\/li\u003e\n\u003cli\u003e2x Bridge Neck 12-Point Nut (RFB-903-RFAB)\u003c\/li\u003e\n\u003cli\u003e24x 5\/8\" Heater Hose (RFB-401-RFAB)\u003c\/li\u003e\n\u003cli\u003e2x 5\/8\" Worm Gear Clamp (RFB-403-RFAB)\u003c\/li\u003e\n\u003cli\u003e2x 3\" T-Bolt Clamp (RFB-422-RFAB)\u003c\/li\u003e\n\u003cli\u003e1x 3\"x4\" Straight Boot (RFB-430-RFAB)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eFitment\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eLLY: 2004.5-2005 (VIN Code 2)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eHow to identify VIN Code:\u003c\/strong\u003e The 8th character of the VIN indicates the engine code.
