6.7L Power Stroke EGR Valve, Pickup (Wide Frame), gen3

Replaces HC3Z-9D475-B.

FOUND 2026-09-16 during a targeted re-check (not the original search): the Ford dealer catalog's 'Emission Components' diagram for a 2021 F-250 6.7L Diesel lists HC3Z-9D475-C as the sole EGR valve - 6.7L Power Stroke EGR Valve, Pickup + Chassis Cab (unified), 2017-2019 (HC3Z-9D475-D) does NOT appear on this gen3 page, consistent with that record's own confirmed 'does not fit a 2021 F-250' finding (2026-09-16). Direct PN lookup shows Fit Note 'Wide Frame (Pickup), With Low Sulfur Diesel Fuel Content', catalog badge '2017-2025', Production Date 'From 07/2016' (same base-number-level caveat as seen elsewhere on this platform - not fully trusted as a per-PN boundary), replacing HC3Z-9D475-B (a different chain than -D's own -A predecessor). Fitment recorded here as gen3 (2020-2025) only, matching the one directly-confirmed data point (present on the 2021 category page); whether it also overlaps 2017-2019 alongside -D is NOT resolved - not guessed. A Chassis-Cab-specific gen3 EGR valve counterpart was not found on this same page and remains an open sub-gap.
