Will this bumper work with the factory fog light openings?

The Vader 2 design features integrated fog light cutouts that match OEM diameter and placement. If your fog lights are currently installed, they will fit through without modification.

Does the lower valance clear the front splitter or air dam I have?

The Vader 2 profile sits lower than stock, so measure your existing splitter or air dam height against the bumper's bottom edge before purchase. Ground clearance varies by suspension setup.

Do I need to prime or seal this before paint?

This Requires Surface Prep, meaning the surface is prepped for paint application. You can sand lightly, apply primer if desired for extra adhesion, then topcoat with your color. No additional prep work is required.
