Will these covers work with my factory fog lights still installed?

Yes. These mount over your existing fog openings — your lights stay functional underneath. If you want to delete the lights entirely, you'd remove them first, then install the covers.

Do I need fasteners to install these?

These mount at factory points, but hardware isn't listed as included. Have basic fasteners on hand or confirm fitment before purchase — you may reuse existing clips or need small bolts depending on your setup.

Are these glossy black or textured?

The finish is factory-ready black, but exact texture (gloss vs. matte) isn't specified. If appearance matters for your build, test-fit and confirm finish before committing to installation.
