The K&N 57-2582 is a cold-air intake kit from K&N's 57 Series FIPK line, designed for the 6.7L Power Stroke V8 turbo-diesel in Ford Super Duty trucks. The manufacturer describes a high-density polyethylene intake tube made by rotational molding, paired with a washable, reusable high-flow filter using oiled cotton media. The kit replaces the factory filter and intake tube, and the manufacturer claims a guaranteed gain in horsepower and torque without a specific figure published on its spec page.
Compared with a stock airbox or a cheaper generic cone filter, the main draw is the reusable oiled filter. You clean and re-oil it rather than replacing paper elements, and the manufacturer backs the kit with a No-Hassle Lifetime Limited warranty. The manufacturer lists fitment for 2011-2016 F-250 and F-350 Super Duty trucks with the 6.7L diesel. Some other listings show a narrower 2011-2015 range, so check your model year and engine before ordering. Search terms that match this kit include 6.7 Powerstroke cold air intake, FIPK intake F-250 2011-2016, and oiled cotton filter Super Duty.

The manufacturer describes the filter as washable and reusable. Owners on user forums recommend using K&N filter cleaner, rinsing dirt out from the clean side with low-pressure water, air-drying the element naturally, and re-oiling it with K&N filter oil. They advise against tapping the filter out, using compressed air, or blasting it with a hose.
The manufacturer supplies an installation instruction sheet, so read it fully before you start. The job centers on removing the factory air box and intake tube and seating the new tube and filter with the included hardware. Owners on user forums describe K&N instructions as sparse, so photograph the factory routing and clamp positions before you disconnect anything. Check that all couplings are fully seated and tight before you start the engine, since loose connections can cause air leaks.
