hi this hks induction kit was on my impreza when i brought it and i have a sort of shhhhhhhhhhhhhhhhhhhh sort of noise coming from the engine bay when excellerating through the gears which it has allways done before i take my foot off the throttle and the dump valve sounds.
The turbo is fine no smoke or whineing and is boosting fine so i was wondering is the noise coming from the induction kit possibly?

Thanks

Adam
