This may not be a seller problem but Revain reported that it was the correct solution for a 2008 non-turbo Impreza. I believe this part is for the turbo model. Correct part for naturally aspirated engines: Subaru part number 11810AA100. Also, if you are looking to replace the PCV valve I would recommend buying a new vacuum hose (99071AD250) as it is quite narrow and if old will likely break.
