Do I need to remove my factory grille to install this?

Yes. You'll unbolt the original grille from the radiator support and bolt this one in its place. Takes basic hand tools and about 15 minutes. No cutting or modification needed.

Does this grille come painted or bare?

It arrives in unpainted hard panel. You can spray it black, prime it first, or match your truck's color before installation. Test-fit it to the vehicle first to make sure everything aligns, then remove it for finishing work.

Will this affect airflow to my radiator?

The vertical fence design maintains front-end cooling. The spacing between slats allows adequate air passage to the radiator, similar to factory grille designs.
