This all-in-one performance bundle transforms airflow and overall efficiency — a must-have for any serious LML owner.\u003c\/p\u003e\n\u003ch3\u003eWhat Is the Max Flow Bridge, Cold Side Tube, and Turbo Inlet Bundle?\u003c\/h3\u003e\n\u003cp\u003eThe factory LML Duramax intercooler piping severely limits airflow, choking performance. The HSP Max Flow Bundle corrects this by increasing both air volume and velocity, which translates to noticeable power gains and improved engine response.\u003c\/p\u003e\n\u003ch3\u003eMax Flow Bridge Benefits\u003c\/h3\u003e\n\u003cp\u003eThis isnt just any bridge.
