The K&N NextGen Dryflow cold air intake, part 50-2613D, is built for the 6.7L Power Stroke V8 diesel in the Ford F-250 Super Duty. It pairs a NextGen intake tube with a reusable, oil-free Dryflow filter, so you clean and reinstall the element instead of buying disposable paper filters. That matters for owners who want a 6.7 Powerstroke cold air intake that avoids oil-related filter maintenance. The manufacturer's fitment listings confirm 2020 through 2023 F-250 Super Duty 6.7L trucks, so verify 2024 and newer model years before ordering. Owners on user forums who have run cold air intakes on 2020-and-newer 6.7 trucks often report a louder intake and more audible turbo, while gains from the intake alone are typically described as modest, with the biggest changes coming alongside a tune.
Installation is a practical bolt-on project for a home mechanic. The manufacturer's general install guide for its intake kits says most can be completed in about an hour with basic hand tools, including a ratchet with extension, 10mm and 14mm sockets, an Allen key, and a flat-blade screwdriver. Disconnect the negative battery cable before starting, and note radio presets and anti-theft codes first, since disconnecting the battery can erase them. Expect to transfer the mass air sensor to the K&N adapter and to tighten the coupler clamps snugly without crushing the sensor housing. Searches like "2020-2023 F250 6.7 Powerstroke cold air intake," "50-2613D intake install," and "reusable oil-free diesel intake filter" will lead to this part.

Plan on roughly an hour with basic hand tools. The manufacturer's general guide lists a ratchet with extension, 10mm and 14mm sockets, an Allen key, and a flat-blade screwdriver. Disconnect the negative battery cable first and record radio presets and anti-theft codes, since losing battery power can erase them. Move the mass air sensor to the K&N adapter, seat the coupler and clamps carefully, and confirm every connection is tight without over-torquing the sensor housing. Follow the vehicle-specific install sheet from the manufacturer for the exact sequence and any heat shield or edge trim steps.
