They are cheap, they are exposed, and they take damage that would otherwise reach the paint behind them.
We stock rear spoilers, roof and window air deflectors, splash guards and stone guards for Kia, Nissan, Mazda and Volvo models.
Deflectors crack and then trap water against the panel they were protecting, which turns a cheap part into a corrosion problem. Spoilers work loose at the mounting points and lift at speed — that is a fitment issue rather than an aerodynamic one, and it usually means the tape or the clips have aged out. Splash guards split at the mounting holes where the liner has been rubbing.
Body style decides the part: sedan, hatch and wagon versions do not interchange even where the model name matches. Check whether the original is a bolt-on or a tape-on type, because the panel preparation is different, and check clearance through the full travel of the hood or tailgate before final tightening.
