Filter fit perfectly. Looking forward to never buying a paper filter again. Thank you

The filter is the first high flow I have purchased. It was for my 2012 F250 6.7 liter diesel. The engine seems to have more horsepower but I have not had it dyno-ed to know for sure. The mileage does not seem to have changed for the better. If anything it seems to be a little lower but more consistent at speeds between 65-80. I can hear the engine sucking more air at lower rpms once it shifts into 3rd or higher with no or very light acceleration.

Very satisfied.

I have only had the filter in the truck for about a month but so far so good. During this time, I have not towed our travel trailer with it in so I can't comment on the upper rpm level performance of it as yet but it will be put to the test in late Feb. early March when we make a trip to Arizona from California. Overall, it went in very easily and it looks very similar to the Motorcraft OEM air filter. Only time will tell how well it performs but I have had K&N filters in all my other trucks before and they performed flawlessly. I have seen a miniscule increase in fuel economy over the past 3 or 4 tanks of fuel that I have gone through since installing it. Hopefully, it will increase a bit more.

I have these in all my vehicle's. They are the best on the market.

Typical high quality, fit and value, as with all K&N products. Everything fit and worked well plus I saw/felt a noticeable increase in upper RPM power without the normal noise (and irritation) of most cold air systems. I have found over decades of using both systems that a simple change to a K&N drop in filter works best for daily street driving plus still adds power in the upper rpm area that is not much/if any less than a cold air system. I have never been dissatisfied with ANY K&N product and will continue using K&N products for all of my vehicles' filtering needs.
