About this part
Cold Air Intake, fitment-checked
A two-year window on the heavy-duty trucks — Silverado 2500 HD and 3500, Sierra 2500 HD and 3500, all 2004-2005 — with one fitment line qualified to trucks running a panel filter.
All four entries share the same short span, 2004 to 2005, which makes the year the first thing to check rather than the badge. The detail that separates this from neighbouring part numbers is in the notes: one fitment line is qualified to vehicles with a panel filter, so the airbox the truck left the factory with is part of the question. California owners have executive order D-269-31 on this part. Construction is 57 Series, a high-density polyethylene tube supplied with a heat shield.
