I always immediately swap the OEM air filters on my cars with K&N drop-in air filters and I love the reusability vs. OEM. This makes them a tremendous value over time, with enhanced performance to boot. My only complaint with this particular filter is that it did not come with the foam element required to fit the factory air box, nor did it come with literature addressing the need to remove the element from the old filter and reuse it with the new K&N filter. Due to the rectangular cutout on side of the filter box, it is not optional to run your engine without the foam element as this would cause excessive dust buildup and negate the air pressure modulation within the air intake. I nearly returned it for a refund until I read the reviews and saw how others dealt with this issue. I highly recommend that, in the future, K&N include some kind of written instructions regarding this for this particular filter. Otherwise, these filters are a great product.

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.
