AIRAID MXP Series Cold Air Dam Intake System; SynthaFlow Oiled; Incl. Intake Tube; Red. The AIRAID MXP Series represents the ultimate in Cold Air Induction systems. Designed for high-performance gas and diesel applications, the MXP Intakes start with a new one piece roto-molded air box that addresses all the shortcomings of the restrictive factory design. Then AIRAID adds a new air intake tube constructed of cross-linked, high-density Polyethylene that is designed using extensive computer modeling to maintain proper mass air flow readings and calibration. They also frequently have a built-in velocity stack, which further promotes airflow.
