K&N Performance Cold Air Intake System: Easy Installation, Engineered to Maximize Airflow, Boost Horsepower & Torque, 57-1532

Install was fairly simple, works great.

I would like to take the time and let you guys know how much I LOVE my K&N. I went with a 57 series cold air intake for my 5.9L Cummins and it has dramatically improved air flow to the turbo. Seemed to just turn the truck into something else!!! It ran better, got better fuel economy and just all around very good system. My dad who has a 2009 Ford F-150 with a 5.4L Triton was asking me about it and I told him it changes the vehicle and the way it acted but in a good way. So he took a gamble and got a cold air intake for his and he told me that he loves it! He took it back to the dealership he bought it from and took the salesman who sold it to him for a ride. All the salesman had to say was what did you do to this thing? That is what kinda of gains he got!!!  I had called customer service with a question and I expected the run of the mill customer service, but to my surprise they had went above and beyond what I was expecting! Very happy and satisfied with the product and service. Would definitely recommend to anyone out there.

Outstanding delivery time. Easy to install. The primary use of this truck is for towing my 32' travel trailer. When not doing that, it mostly just sits. I probably haven't put more than 20 miles on it since the installation. I'm taking a 5,000 mile trip next month and looking forward to finding out how it works when towing that distance. I'm hoping for better mileage, as well as a bit more power.

Easy install and great quality parts. I've seen fuel mileage increases close to 2 mpg and a lot of HP gains. The truck runs much better after installing the K&N air intake.

Very happy with my new intake, increased fuel economy, power, and she whistles alot more. Very happy with the new sound!I Would recommend this product to anybody looking for more power or whistle in their truck!

Awesome kit by K&N. It was simple to put on and came with all the parts required. Definitely gives the truck a lot more responsiveness and it's always nice to hear the turbo a little more. Couldn't be happier.

This product was exactly as advertised and gave my truck a very noticeable horsepower increase. Very impressed with results for the money.

The intake kit was delivered on time. The installation was simple and with minimal time. The kit worked as advertised.

Kit was easy to install, and it is performing well. Performance has increased and fuel mileage has went up.

I just installed the intake system and can tell the difference by the end of the day. I am very impressed. Installation was easy. Thank you
