i knoe i already ask this but no one replied if it was normal it is like a scraching noise only when i start mb even when i am cruzing mb car to loud to hear.
should i re install the CAI eill that help

it maybe the hole you cut is not big enough, and the CAi is scratching against the car, when you accelerate.

 

My intake was hitting the fender and kept clicking against it. Tightening the retaining screws and a little bit of double sided tape fixed it.
