Fram use to advertise the Ultra as both layers being "full synthetic" so I wonder if they have changed the media some. Right off Fram's website it still says for the Ultra media:
"2-ply synthetic, metal-screen-reinforced media provides 99%+ filtration efficiency." No mention of cellulose media there.
However, this pretty new video (Jan 4. 2019) does mention (time 30 seconds) synthetic and cellulose media.
