Will this cover my fog light cutouts from the factory bumper?

No — this bumper cover retains the factory fog light openings. If your stock bumper has factory fog holes, you'll need to transfer or recut them to match this cover's existing light cavities.

Are there sensor holes pre-cut for a parking sensor?

The raw bumper does not ship with pre-drilled sensor holes. If you run parking sensors, you'll need to carefully drill and fit them after receiving the cover, or drill before painting.

Does this work with my lower valance or splitter?

This cover mounts using factory attachment points and has an integrated lower air dam. Aftermarket splitters or valances may require test-fitting or minor modification to sit flush without interference.
