Kevin, I do have a compressor, I think next time I will give that a try, although it did look like some water had splashed into the air box but not too much, you could see a stain if dirt water had settled on the bottom. But I'll try that next trip.
Steve, I still have the fender liner in place, I haven't removed it yet so it shouldn't be getting a direct blow of the dirt, but since it's by the fender then it makes sense it's picking up dust anyways. Did the Snorkel make a considerable difference or minimal for the process involved?
