High-Flow Air Filter for Ford E-350 & E-450 (2021-2026)

About this part

High-Flow Air Filter, fitment-checked

The cutaway and chassis end of Ford's line: E-350 Super Duty and E-450 Super Duty, both covered from 2021 through 2026 on identical year spans.

Both entries here are Super Duty vans, the E-350 and the E-450, and both run the same window from 2021 to 2026. Fleet buyers get the simpler version of the fitment question as a result — the two chassis weights share a filter and a span, so only the model badge separates them and neither carries a trim or engine qualifier. The part is a high-flow original lifetime replacement air filter, swapping directly for the factory element. K&N records the warranty class as No-Hassle Lifetime Limited.
