hi ive had my scooby. (1995 wrx) for a few weeks now, must say its a amazing motor im really happy with it . at about 80-90 mph ( on private roads ) there is like a vibrating/buzzing noise coming from the front of my car. is this just the air going into the scoop ?? thanks

 

Yeah i think it's air coming in the scoop and missing the intercooler and trying to force it's way out past the rubber seal between the bulkhead and the bonnet. mines even worse now i've removed the TMIC and have a FMIC.
