5 Star Review
My 2019 Dodge Ram 1500 5.7L came to life all over again with this. I went from around 19.5 to around 24 mpg. It helps tremendously with power etc. when pulling. I would recommend this to all!

Worth every penny
I love this intake. You can hear it. It looks awesome under the hood compared to the stock one. And the added performance is great. I even noticed better mpg.

2022 Ram 1500 5.7L
Easy to install, fits well and looks good. Nice sound under acceleration. It needs a decal or K&N emblem on the tube.

K&N Cold Air Intake
The fit and finish is second to none what you would expect from K&N. The black K&N sticker does not come with purchase. Paired with a good exhaust system you are guaranteed Hp gains, torque gains and better gas mileage if tuned properly.

Waste of time and money, zero stars,1,000,000 thumbs down
After installing this on my truck, my gas milage has gone way down. No increased performance, no increased horsepower. I tried contacting K&N and got no response. No support either. Garbage!
