Generally it’s fine to remove those but I would consider having it put back on if you live anywhere that gets snow. Reason being is that this plate protects undercarriage parts from excessive corrosion as a result of salt on the roads. So your car isn’t going to break down if you remove it, but if you plan to keep the car long-term, it can extend the life of those parts. As someone who works on my own car and has also had several 15+ year old vehicles, I can attest that this plate does indeed reduce corrosion in those areas.
