2004 stock wrx wagon, 120K miles, no mods outside a drop in K&N filter.
This is the wife's car, so I don't drive it all the time (I commute on a motorcycle) but the car just doesn't feel as quick. After reading through some of the posts, I'm thinking a boost leak?
The car drives fine, no stalling, no shuttering, it just doesn't accelerate like it did at above 3K rpm it lost the sling shot feel it once had.
I'm going to check for any clear signs of leaks but need help where to look? Any common failure areas? I'm assuming the leaks could come from the pipes from the airbox to the turbo and from the turbo to the intercooler? I'm assuming these pipes are made from rubber. Where else should I be looking?
Any feedback would be great.
