I'm running a 4" inlet conical AEM dryflow on the custom single turbo system on my Supra for the past 3,000 miles or so and I found a light coating of very fine dirt in the entire intake tract from the filter to the manifold. It's enough that I immediately noticed it when I pulled the intercooler pipes apart (upgrading the intercooler again). I can swipe my finger in a pipe and my finger tip is dirty. Everything was brand new and completely clean when I started using this filter, no intake or boost leaks or any other way for dirt to get in other than through the filter media. Back on the stock turbos I was running a much smaller oiled k&n and never saw anything in the pipes like this. The only other factor that could be at play here is that the filter sits behind the headlight opening and is directly exposed to rain. I try not to drive the car in rain, but it did happen a few times. Could water be washing the captured dirt out of the media into the inside with this type of filter?
I've now noticed that they sell hydroshields for them and will be getting one but I'm curious if anyone else has experienced similar.
