Will this fit if my bumper has sensor or fog light cutouts?

This is a full cover, so any existing holes in your current bumper will need to be re-cut or drilled into the new panel to maintain OEM functionality. Check your vehicle's current bumper layout and transfer those hole locations to this cover before install.

Should I paint this before or after installation?

Painting after installation is cleaner — you avoid masking and tape lines on bolted seams. Sand and prep the surface, apply primer, then color coat once mounted. This also lets you blend the paint with your fenders and hood for a factory finish.

Does this work with a lower valance or splitter?

Yes. The bumper cover leaves room below the main panel for aftermarket valance kits or splitters. Verify the fitment of any lower aero pieces with their supplier — bumper height varies depending on how you mount this panel.
