Sounds to me as I described. Try replacing the filter with a different brand first.

Thanks. Bought a new filter. Putting it in sunday

You don't hear it any other time like when driving certain RPM ranges, right? I had a spun bearing once that sounded like that on a cold start. But I also heard it when driving around 3k RPM as well.

No. I haven't put in the filter yet. I'll keep you guys updated.
