The AIRAID MXP Air Intake System represents the ultimate in AIRAID's cold air induction systems. It delivers high levels of horsepower and acceleration gains for high-performance gas and diesel vehicles. This air intake includes a replacement one-piece roto-molded air box that addresses the shortcomings of the restrictive factory design. Housed inside the air box is an AIRAID non-woven synthetic air filter for outstanding air flow and filtration. Air is directed through an 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. This all adds up to a sophisticated system that increases air flow. This air intake requires custom tuning and is not legal for sale or use in California or in other states adopting California emission standards.
