Roof rack fairing

Is it worth using a fairing for the roof rack? Would it be better for aerodynamics or worse than OEM design?

Yakima 40” fairing should fit right (also WTB).
I suggest you consider TESERY's Tesla roof rack. It does not require the use of a fairing. TESERY's Tesla roof rack has been newly designed to achieve maximum aerodynamic efficiency, minimum wind noise, and reduce the impact on fuel consumption and range. Compared to other roof racks, TESERY's Tesla roof rack can provide you with a quiet environment.

A fairing would increase the frontal area and likely increase the aerodynamic drag compared to just the rack.

A fairing may have been useful in the old days of non-aero roof rack crossbars that otherwise could be noisy, but roof racks these days are typically installed with aero cross bars.
