Do the fog light holes match my factory openings exactly?

Yes. The cutouts are pre-positioned to align with stock fog light locations. If your bumper has existing holes, this cover will line up without modification. If painting, mask off the holes first to keep paint clean.

What condition is the chrome finish in when it arrives?

The cover ships with a polished chrome-plated surface. You can install it straight out of the box or lightly polish before mounting if you want maximum shine. No primer or basecoat is needed for fitment.

Will this work if I have aftermarket fog lights?

It depends on the light size and mounting depth of your aftermarket kit. Test-fit the lights through the holes before final install. If your lights sit deeper or wider than stock, you may need to adjust or enlarge the openings.
