Will this interfere with the bumper's sensors or parking camera?

The splitter mounts to the front fascia below the sensor zones. You'll want to visually confirm clearance before final installation, particularly around any parking sensors on your specific vehicle. Test-fit first.

Does this need paint prep before I install it?

It arrives in matte black and ready to bolt on. If you want a custom color or glossy finish, you can prep and paint before or after installation—just avoid getting adhesive residue on mounting surfaces.

What fasteners do I need to attach this?

The lip uses your factory bumper mounting points. Bring basic hand tools and inspect your existing fastener hardware before assembly; you may reuse OEM bolts depending on their condition and the specific mounting design.
