Had my Wrx for about 2 months now just recently started driving it regularly. Anyways im at about 750miles havent really pushed the car to hard...The noise I am hearing sounds like my intake is sucking in air but the thing is I just started hearing the noise it didnt happen before. Its on the passenger hand side and the noise comes in at about 3k rpms I dont really hear the noise in 1st gear or 3rd. I might just be a little jumpy but im pretty sure I didnt hear the vacuum like noise before. Thnx for your help in advance.
