Will this work on vehicles with factory parking sensors?

Yes. This deflector is designed around factory sensor placement and won't interfere with bumper-mounted sensors or their operation.

Does this mount to the lower valance or the bumper cover itself?

It attaches to the front bumper assembly at factory mounting points. No drilling required—uses existing attachment locations.

Should I paint this before or after installation?

Test-fit it first to confirm alignment with your bumper. Paint after installation so you can match edges and ensure a seamless finish with your bumper cover.
