Follow these steps carefully

Identify the generation before you buy anything — a W639 filter will not fit a W447 box, and I've seen people order twice because they skipped the VIN check.
Van housings see more heat cycling and road grime than car boxes, so work the fasteners gently and do not pry the lid until every one is free.
Lift the old panel filter out and note which face is dirty to set the airflow-arrow direction. Van airboxes collect an unusual amount of debris — vacuum the lower housing thoroughly for leaves, insects, and fine dust that accumulate behind the grille. Inspect the lid seal for hardening, check the intake duct and its clamps for cracks from heat aging, and confirm the MAF sensor connector is clean and dry. If your van is an older W638 or W639, the housing layout differs, so compare the new filter against the old one before proceeding.
Set the new filter into the lower half with its gasket fully captured in the channel and the airflow arrow matching the old element's dirty side. The panel must sit flat with no rocking; on the W447 a filter that stands proud means the wrong generation's part. Lower the lid straight onto the seal, seating it squarely before engaging any fasteners — never use the clips or screws to drag a crooked lid into place.
In my experience, if the lid sits crooked, don't drag it straight with the fasteners — lift it and reseat it square. Using the clips to force a crooked lid warps the seal channel.
Engage every lid fastener with even tension so the seal compresses uniformly, then confirm the MAF connector is seated and its wiring clears the lid edge. Remove the towel, start the engine, and listen at the airbox for a hiss or whistle that would signal an intake leak. Verify there is no check-engine light, no rough idle, and no loose-housing rattle at idle and under a light rev before you close the hood.
Test your repair before closing everything up. If something doesn't work right, double-check your steps.
