No, a 2007 Subaru WRX STI bonnet will not fit onto a 2010 Subaru Impreza RS. The two models have different body styles and dimensions, which means the mounting points and overall shape of the bonnets differ. Additionally, the STI bonnet may have features like vents or scoops that are not compatible with the Impreza RS design.
