Aerodynamic Roof Cargo Box (16 cu ft)
Retailer links:
Sleek roof-mounted cargo box. Minimizes wind noise and drag. Includes roof rails.
Buying Guide
Mounts on all four models — 3, Y, S and X — and ships with its own roof rails, so you don't need Tesla's factory bars first. That said, the S and X have different roofline and panoramic-glass clearances than the 3/Y, so verify the rail spread against your specific roof before the first trip. The 16 cu ft box is a single unit, not a pair.
A medium two-person job: assemble and clamp the rails, set the 28-lb empty box, then torque the mounts evenly so it sits square. Before buying, know that any roof box adds drag and cuts range noticeably at highway speed on an EV, and the added height affects garage and car-wash clearance. Load heavy items low and centered, and never exceed Tesla's roof weight rating regardless of the box's own capacity.
