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 specific Dodge Ram 1500, 2500 and 3500 models. This air intake starts with a replacement one-piece roto-molded air box that addresses all the shortcomings of the restrictive factory design. Housed inside the air box is an AIRAID 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. This MXP air intake system incorporates fresh air ducting, which further promotes airflow, and has provisions for the factory crankcase vent tube. 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! This air intake system is backed by AIRAID’s No Hassle Lifetime Warranty. Some AIRAID air intakes are not legal for sale or use in California and other states adopting California emission standards, while others are 50 state legal.

September 6, 2016 - Part 301-237
The installation was simple and all of the parts were included with no issues. The only item that I did not like was the filter installed with the metal seam on the top, where it is visible. I would have liked it better if the seam was on bottom where it is not visible. I was not able to turn it because the opening is offset and it would not fit in the box. Noticable difference in power and mileage increased by 2-3 MPG on the highway. Stop n go driving took a hit and actually decreased from factory. Sound is nice though. Overall satisfied. It is too expensive in my opinion, but had to have it.
