Style: Dry Flow
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.

Just bought and installed this Cold Air Intake (aluminum tube) on my 22 RAM 1500 5.7L. The install only took about a half hour. I'm certain it could have been quicker, but I took my time and followed a video on YouTube. I preferred that over following the directions provided. To me, they weren't detailed enough. The video set me up for success and was easier to follow when I needed a reminder of the next step. Once install was done, I started the truck and it purred. I had taken it for a drive the night before and yeet around listening to the sound and getting a feel for the vibes and handling. I noticed a difference immediately. The truck definitely has more power. As I took the first turn on to the interstate, I was a little ambitious with the accelerator and actually got a little spin at speed that made the truck work a bit. The Mikey Thompson's were gripping the road and it felt great. The sound was so good. I could feel the grin on my face and headed straight for the interstate, and open roads. I tooled around for a while and was consistently surprised by the difference. The truck was good as it was, but now it's great. I'm excited to tow. The trucks name is Sass, she's living up to the name now more than ever. I couldn't be happier. I was looking at different option, and now I don't feel like throttle controls and what not are necessary. I'm happy and even more excited to drive my truck!

First one I received seemed to be used or previously returned, but return was smooth and 2nd one came the next day. Easy installation, feels smoother, and added a nice small intake sound.

2022 Ram Laramie, For the price you pay honestly expect new it did have a few hiccups however nothing major that would make me wanna return it. Didn’t have any issues installing and have noticed so far it has helped with the fuel mileage on my truck.

The media could not be loaded. I already have one on my 2014 RAM 1500 R/T so we got one for our second RAM. It's a 2023 RAM 1500 BigHorn 5.7L Hemi V8. The performance is much better with an increase in fuel efficiency of about 5mpg highway and 3mpg city. It fits perfectly but be sure to follow the directions as you need to take some pieces off the old system for this new one. Excellent value for the money and it sounds cool when you give it some gas! Filter lasts a long time between cleanings. Get the recharge kit from K&N for the cleaning solution and oil.

Purchased a new product, but was sent a used/returned product. The interior of the pipe was stained, and a plastic piece broken off in the metal threads. This cannot be installed as-is. I've always loved K&N, but this is horrible. They shouldn't be selling returns as new, and they should be inspecting their returns thoroughly. I'm trying to get a hold of customer support to resolve.
