Standard Wix (NAPA Gold) work fine on my Tucson.
Just put on an oversize 51344.
Plan to leave it for two 4-5000 mile OCIs.

How do we know they "flow better"? Nobody here has ever seen a flow test - ie, a delta-p vs flow rate curve.OEM filters with mediocre efficiency (more flow, less cost?) seems to be an Asian philosophy.
Toyota and Honda filters for example.
Just to be clear, I do not believe that low efficiency filters necessarily flow better.How do we know they "flow better"? Nobody here has ever seen a flow test - ie, a delta-p vs flow rate curve.
We've seen flow data from @Ascent Filtration Testing of some synthetic media filters. I doubt that low efficiency filters flow any better. They could actually flow worse (meaning more delta-p vs flow), and their efficiency could suffer becsuse the media can't hold what it has already captured. It's discussed in the big testing thread.
The Walmart near me has the OEM Hyundai/Kia oil filter (part no. 26300-35505) on the shelf most of the time.When I was at Walmart last weekend, they had a Hyundai OEM filter on the shelf! Surprised the heck out of me.
Anyway, I found the Fram Ultras ran very quietly on my Sonata when I had it. Prior to that I had always used OEM on the Sonata, my Kia Spectra and my Kia Rondo. Same filter for all three.
Surprises the heck out of me that someone can _hear_ the difference between 2 filters. Helluva ears! Maybe the Sonata just coincidentally runs quieter for some other reason when you have this filter on. I could not
come up with a theory how the filter could make an audible difference, no matter how good. To be clear I am a fan of the Fram UG-s.
