AIRAID MXP Series Cold Air Dam Intake System: 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. What this all means is a simple-to-install system that was designed using extremely sophisticated technology to increase airflow while maintaining proper air / fuel ratios, therefore eliminating the need for re-calibration once installation is complete. Just bolt it on and go! Like any other AIRAID® Intake System, the MXP includes an AIRAID® Premium Filter that is sized to maximize power and efficiency.Fits:CHRYSLER 300 2011-2015 V8 5.7LDODGE CHALLENGER 2011-2015 V8 5.7LDODGE CHARGER 2011-2015 V8 5.7L
