Installation of the MXP model into my 2006 Dodge Ram 3500, 5.9L Cummins was much easier (and more fun) than I'd expected. Airaid's design, step by step instructions, and quality parts are all world class, down to every detail of every fastener. ok, so does the system do what it claims to do? As far as I can tell yes. Given that Cummins had truly perfected the 5.9, I did not expect much of an increase in mpg. I've had in installed now for about 2 weeks, and have only run the truck unloaded (I load it with a fairly heavy camper). With the factory air box unloaded I was averaging 16-18mpg. With the Airaid I am getting over 19. The real test will come when I go on a trip with the camper. The truck does have a slight but noticeable increase in 'get up and go'. I did call Airaid with a couple of questions (the unit seems to make a slight whistle sound, which is no problem). Their tech person was very knowledgeable. World class product, world class service.
