I was photo documenting the oil change on my Corolla when I noticed something I didn't like about my Purolator provided L16311. The media junction doesn't quite line up, but more importantly, the adhesive/compliance material on the ends wasn't smooth. It was bunched up near the joint, on both ends, as if it sagged from gravity during application.
I took out my dial calipers and the difference between the high and low sides was .064". I'm not sure how much crush compliance there is with this material, so I decided not to install it and went with the Denso instead.
Denso on the right in these pics. Dirt on new filter is from my hands, from draining the car.
