The K&N 50-2600D is the NextGen Diesel Dryflow cold air intake for the 6.7L Power Stroke V8 in 2017, 2018, and 2019 Ford F-250 and F-350 Super Duty trucks. It is a complete cold-air intake system rather than a simple filter swap, and K&N lists it as the direct match for those model years. For buyers searching for a 2017-2019 F250 6.7L Powerstroke cold air intake or a 50-2600D NextGen diesel intake, that model-specific fit is the main reason to choose it over a universal kit that may need trimming, adapters, or guesswork.
Compared with the factory setup, the advantage is a purpose-built intake for this exact engine, backed by K&N's engineering. K&N's lineup also includes other intakes for these same trucks, including the 57-2600 and 63-2600, so you can compare filter design and housing style before ordering. Airflow gain, tuning requirements, and tube material were not confirmed on the manufacturer's listing, so confirm those details with K&N before you buy if they factor into your decision. K&N also lists a separate NextGen Dryflow intake, part 50-2613D, for the F-250 6.7L, so verify your model year before ordering.
The manufacturer's fitment pages list the 50-2600D for the 2017, 2018, and 2019 Ford F-250 and F-350 Super Duty with the 6.7L V8 diesel.
The manufacturer lists the 50-2600D for 2017-2019 models only. For the F-250 6.7L, K&N offers a separate NextGen Dryflow intake under part number 50-2613D, so confirm your model year before ordering.
