Checked Air Filter and Found

Its been a long time since posting here but I need your opinion.

I just checked the air filter for the hell of it last weekend as I bought this pre-owned a year ago.. Of course it looks like a normal filter but it also has a glued on sheet of maybe 1/4 inch filter like material on the air filter.

Has anyone every seen this before? Seems like overkill and certainly can't help for both power and MPG.

Yes. I found the same with my original filter. A replacement (Fram, I think) also has this odd feature.

Is it before the normal filter media? Possibly just a prefilter of sorts to keep the large stuff from getting caught in the pleats. If not, I have no idea.

I noticed the same thing when I changed mine. I believe it is a pre-filter for the main filter....I assume it is just a way to make it more efficient. I will catch the larger stuff and leave the main filter for the small stuff. Probably gives a very small boost to the mph, although that is just a guess. In theory it should allow the engine to breath easier.
