K&N Performance Cold Air Intake System: Easy Installation, Engineered to Maximize Airflow, Boost Horsepower & Torque, 57-2546-1

Easy access to airfilter

I purchased a K&N air intake for my 2005 Ford F-350 6.0L Diesel from an online source.  When I received it, I realized that there was a problem with the fit of the top.  I contacted the online source and K&N.  K&N stepped up and immediately responded with a new kit.  Thank you K&N.  This makes vehicle number 5 that runs with K&N - Ford, Chevrolet, Chrysler and Hyundai.

Got my part in quickly after order. After install, you could feel the power gains and the breathability. It makes the inside of the truck a little louder, but that's expected. Since install, which was just recently, we've already put 500 miles on it, and it's been preforming very well. K&N, you will always be my store for quality air parts.

Great increase in towing performance! While towing 5th wheel in Bighorn Mountians in WY during July, air intake temp was running at less than 120 deg. during a one hour climb. Seems to have increased MPG, but haven't done accurate testing. I recommend installing high performance intake as one of the first mods on a 6.0 Ford diesel.

Immediately noticed the power difference once the cold air intake was installed. Second cold air intake I purchased. My previous purchase was for my 2004 Trailblazer. Excellent results with that install and I am sure this one will be no different.

This was VERY easy to install, took less than an hour. Everything fit amazingly well. There is a noticeable increase in power while towing the horse trailer. There is a little more noise in the cab, but not bad, it just sounds different. Overall I'm very satisfied.

Started working on it late at night and finished up first thing in the morning. Used the paper instructions along with the online you tube video instructions and it was pretty easy to install. I noticed a big difference in the sound and performance of my F250 right away.

I noticed a difference from the beginning, but really noticed a big difference towing my 5th wheel RV in the mountains. Big increase in HP. Mileage was not greatly affected. Overall, I'm very satisfied with the results.

After straight piping and the K&N filter in my '05 Ford dually, I feel like a kid again. (can't tell if I'm getting better mileage cuz I can't seem to keep my foot out of it!)

It gives my truck so much more than the stock intake filter. It's responsiveness is very nice. The truck sounds much nicer also. I catch myself having to slow down even, it gets me to 80mph in seconds. I couldn't be happier.
