The AIRAID MXP Air Intake System represents the ultimate in AIRAID's cold air induction systems and delivers higher levels of horsepower and acceleration gains for high-performance gas and diesel vehicles. Some AIRAID MXP Air Intakes start with a replacement one-piece roto-molded air box that addresses the shortcomings of the restrictive factory design. Housed inside the air box is an A IRAID premium air filter for outstanding air flow and filtration. Air is directed through 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. Many MXP Air Intake Systems have a built-in velocity stack, which further promotes airflow. What this all means is that you get a simple-to-install, yet extremely sophisticated system to increase air flow while maintaining proper air-to-fuel ratios, thereby eliminating the need for recalibration after installation. Just bolt it on and go!
