I haven't heard of it either. Would be concerned with how well it filtrates, and flows. I would personally recommend going with the 6637 mod; I had very good results from day one.

Yea, not to mention that it can be the stock air box that can leak, and cause poor filtering too.... I'd say to stay away from drop in filters. I would also vote for the 6637, or if you are concerned about warranty issues, an AIS.
tell ya what, this filter, true flow, sure does look rigid and thick. I know that does not mean diddly, but im just saying. Cant help but to have a tight seal because of the way the lip is made 1/2 inch of foam rubber. nevertheless, i still have it in the box and Not on the truck cause i just dont know anything about it.
off topic, was the problrm with the k&n due to poor filtering or a poor seal(failing to fit the air box)
