K&N 30-1578 Performance Air Intake System, Dry Flow. I installed my system on a NEW model 1500 RAM Limited with the E-Torque Hemi. Purchased a Dry Flow intake so I would NOT have to clean and oil the filter. It also has the plastic or Roto-molded intake tube. I essentially followed the advice given by AKT in his review. Go slowly and FOLLOW the directions. Uninstalling the stock air box was the hardest part as I was really trying to not break any plastic parts. Everything else was easy and done quickly. The first of two tips I can give is to remember, or take a picture with your phone, of the air sensor position. It is reinstalled using a rubber grommet and can be easily turned to the correct position in the intake tube. The second is to go slowly when installing the K&N air box. Be sure to line up the intake opening in the air box with the grill intake as these two mate with a foam seal that seals everything off from the engine compartment. My wife was surprised when I came in from the garage as she thought I would be hours installing the K&N system. More good news is that after a week or two my mileage is inching up. I was getting an average of about 14.5 around town with the stock system. I am now getting 15.7. This is looking at the mileage compiled by the RAM, no scientific measurements. I have noticed better acceleration, a little better mileage but I really wanted this system for the torque gain when I tow a trailer. It does sound louder but not very much compared to my old GMC with K&N intake with an oiled filter when accelerating hard. It is quieter when cruising (about like the stock system) and my wife likes that. I will update this portion of my review when I take the trailer out in the spring. I’ve been using K&N products a long time and have never been disappointed. Friday, 3 May, 2024 It has been a few months now and I need to update my review. I cannot talk to increased torque, but my RAM truck is telling me my mileage has increased. The driver information center is saying I am getting a solid 15.9 mpg around town, up from a 14.4 mpg with factory intake. The really funny thing is at 70 MPH my indicated mpg goes up to over 20! At 60MPH I am getting an indicated 18+. These are the averages given out by the Ram info system. I did NOT manually calculate the mpgs given. ... show more

    • I was expecting perfection from a company like K&N
Style: Dry Flow
Missing parts Missing grommet for air sensor and Missing the rubber trim for the top of the filter housing . It seems to me that they shipped an open and previously returned item ! Because of this fact alone , I just can't give them more than 2 stars in my review
