K&N Replacement Air Filter

This Filter, Air Cleaner, E-0644, is a direct replacement filter for a 2017 F450 Superduty and 6.7L Powerstroke Motor. I have purchased K&N Air filters and a Cold Air intake for another vehicle in the past and have had very good performance results. The F450 uses a paper filter with an attached sponge foam block filter to equalize pressure in the air cleaner housing. The FoMoCo replacement air cleaner is $96+ and the K&N replacement cotton material, reusable air cleaner cost $105. One time purchase. The Foam block insert is necessary to complete the install and I carefully peeled the original foam block from the paper filter with no damage to the foam block. I then washed the sponge foam block in mild dish detergent and allowed it to dry. Installed the new K&N with the sponge foam block. A good tight fit but no problem on the install. Noticed immediate performance gain from the flow of air being less restricted by using the K&N replacement. Put a little cetane boost in with my next fuel-up and I must say that the combination is a winner. Seem to have picked up about 2mpg and a significant performance increase when demanded. Pleased with results. Good investment.

Product shipped in a timely manner. Was easy to install and fit properly. Don’t know about fuel mileage as I do not drive truck enough to worry about it.

I run K&N filters in all my vehicles either bought online or in store and as always I’m always satisfied with the performance of your products.
