Well, I just checked my Pro Dry filter after having it in my car for 4,000miles, which isn't much, but I've been through a lot of dusty areas lately. I'm sad to say this one is no good. Unfortunately my camera isn't working, so no pics. There is a raised ridge around the edge of the urethane part of the filter that fits inside a groove in the top part of my air box, the clean side of the filter. That ridge was covered in dust, but I did not see much past that point or inside the air box lid. I though, well, maybe the inner lip of the groove in the lid is still sealing against the urethane. I cleaned the dust off the filter, coated the inner lip of the lid with oil and put everything together agian. I removed the filter again and there was one spot about and inch long where the lid left oil on the filter. So, looks like I was right to worry about the AFE filter not seaming as thick as the factory Denso filter, so back in went the factory filter. This makes me sad, this is the first time I've ever had an issue with an AFE product. I'd like to contact them about this, but unfortunately I don't have any pics of the filter before I wiped the dust off of it so I'm not sure that they would do anything about it.
