This is a Mazda 3 OSF wing, designed specifically for Mazda vehicles. It is a body side panel that fits on the front right side of the car. It is a genuine Mazda part for replacing or upgrading the drivers wing of a Mazda 3 model.

Please make sure this fits yours - there are two different types which vary at the top - I didn't check and this is why I have this!  No returns, sorry
