Plenum Front Panel – GM (84261404)

This is a plenum front panel from GM, factory part number 84261404. It is catalogued under Covers & Caps > Panels & Plates.

• Covers that seal a fluid opening normally carry a single-use gasket or O-ring, and reusing the old one is the usual reason a leak comes back.
• On panel and plate parts, check whether the original is held by clips, screws or both. The fasteners are often sold separately and are often what actually broke.
• A cap that vents and a cap that does not are visually similar, and swapping them gives a fault code or a pressure leak rather than a fit problem.

Corrosion at a mounting face is worth cleaning back before fitting anything new, because a part that sits on scale will work loose.

The part number is the thing to verify. Where the old part carries no legible number, a VIN and a photograph are enough for us to identify it. In stock and sent from the US in one to two business days, free delivery over $59.
