Question for you now...

Is the end of your air filter contacting/vibrating against the plastic wheel well liner? I have my turbo system pushed as far up and towards the driver side as the down pipe mounting bracket will allow, but my air filter still firmly touches that liner. My liner is slightly pushed out of its natural resting position, and I get an annoying vibrating noise from it at certain RPMs.

I really need to get this taken care of because I want to use a water-repellent pre-filter bag on my air filter. The contact between the filter and plastic liner has already worn a hole through one.
