6.7L Engine Air Intake Secondary Foam Filter

There are a few threads concerning this issue, but I found an article that best explains the use, purpose and location of the Ford 6.7L Secondary (Pre-Filter) Foam air intake filter.

It is a NAPA Article. https://napafilters-z5jsk59bxkjskm52p5f.stackpathdns.com/wp-content/uploads/July-2015-NAPA-500139-HD-Air-Filter-English.pdf

The below pointer works when I put it directly in a browser

It appears the foam secondary filter is in place in case the primary filter intake is blocked (i.e. snow). The secondary filter allows air in while the primary is being cleared.

Ford (Local Dealer) Recommends replacing the foam filter when replacing the primary if needed.

I thought the Secondary (Pre-Filter) Foam air intake filter could be washed if not damaged?

Good info. I completely forgot about mine when I recently changed my air filter. I"ll have to look at it to see if it's in good shape or not.
