The K&N 33-2313 is a panel-style, drop-in replacement for the 6.8L V10 in 2005-2007 F-250 and F-350 Super Duty trucks. K&N's washable, reusable High-Flow filters use layered, oiled cotton media engineered to improve airflow and capture contaminants. Each filter is reusable and backed by K&N's No-Hassle Lifetime Limited Warranty. The case for paying more than a disposable paper filter is long-term cost. One V10 owner on a user forum said the K&N saves money over paper filters over time.

Set expectations on performance. One owner who installed a K&N on a V10 said they did not really notice a difference in MPG or horsepower. Another owner reported nothing noticeable in a Super Duty. The bigger concern is oiled media. Some owners on user forums have reported mass airflow sensor contamination from oil-coated filters. Other owners said cleaning the sensor wire may solve the problem. Keep the stock filter nearby while a freshly cleaned K&N dries, as owners suggest.

Yes. The manufacturer describes it as washable and reusable, and it is designed to be re-oiled after cleaning. The manufacturer's re-oiling amount for this part is 2.55 oz (75 ml). Confirm the recommended cleaning interval with the manufacturer, since it was not confirmed during research.
Owners on user forums have reported sensor contamination from oiled filters, and some reported that carefully cleaning the sensor wire resolved it. Clean the filter thoroughly, keep oil off the sensor side of the airbox, and let the filter dry fully before reinstalling.
This is a drop-in swap. The manufacturer says the filter is designed to install easily into the factory air box, so no modifications should be needed. You will need to open the airbox lid, remove the paper filter, and seat the K&N in its place. Owners on user forums suggest keeping the factory filter on hand while the reusable filter dries after cleaning. Keep oil away from the mass airflow sensor. The manufacturer's install sheet for this exact part number was not retrieved during research, so check the sheet that ships with the filter for orientation and sealing steps.
