Does what it says 😤
The Next Gen is awesome! Install truly is a breeze. Just take your time, nothing fancy. This air box completely and totally changed the sound of my hemi. It gave it a gutter roll growl from the front end. And the torque and horsepower gain is very noticeable.

All Smiles.
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!

K&N Next gen: 5.7 HEMI
K&N next gen Installed on a 2022 Ram w/ 5.7 HEMI It installs in minutes, takes minimal mechanical effort. It made the sound so much better, deep growl when you push the loud pedal down. I can really feel the extra power at about 45-55 mph when you accelerate. Don’t know about fuel efficiency, it’s a 5.7HEMI so, yeah I don’t care about fuel efficiency.

2021 5th Gen RAM 1500 5.7
I love the sound and performance i gained from this K&N . It was more than I expected. Gas mileage went up slightly too. Im giving a 4 because my filter came with some crease’s in it and the tube had some small scratches. It could have been packaged better. Overall it’s awesome.

It's worth it
This intake system is for the new RAM body style, not the "Classic." The instructions provided by K&N are pretty good, FOLLOW THEM IN ORDER. Estimated time to complete: less than one beer. What you need: For the hose clamps- 5/16 nut driver(recommended) or minimum size of 1/4" flathead screwdriver For the vehicle's negative battery terminal- 10mm combo wrench or adjustable wrench or 10mm socket w/ratchet For the K&N PCV fitting- 19mm combo wrench(not required if you can open a jar of pickles) For trimming the form fitting gasket- Shears or diagonal cutters or sharp utility knife For the Filter/collar coupler- 5/32” hex wrench Four things to be gentle with during the removal and install: the air flow sensor connector, the PCV disconnect, K&N PCV fitting, and the air box removal. After following the K&N instructions that get you to the point of loosening the hose clamp on the throttle body, RESIST the urge to leverage or twist the air box out, you will break the (4)molded plastic post it sets on. The one deviation I will recommend is to ONLY HAND TIGHTEN the K&N PCV hose fitting. I threaded mine all the down by hand. You'll likely end up horse cranking on this thing if you use a wrench and will break it off like others have done. It has a deeper, guttoral sound once you creep up on 3k RPMs throughout the remaining RPMs of the motor. If you drive it like normal, you will see an increase in your fuel economy. Without a dyno of before and after, I can only take K&N's word for the ~15HP increase in a near 3-ton vehicle. The torque increase @ ~35 lb ft is very good for a truck to use for hauling though. I'd recommend the upgrade on your truck. I feel it is worth it and over the life of the vehicle you'll get more bang for the buck versus stock air filter replacements. KEEP YOUR OEM AIR BOX. WHEN YOU SELL YOUR TRUCK, PRIVATE BUYERS/STEALERSHIPS WANT THAT.
