These are pictures of a K&N PS-7022 cartridge filter off my 2008 Sedona. Engine had 80,150 miles at time of change, and OCI was 6 months and 7,300 miles with TGMO 0w20. I can't help but notice that the filter looked slightly caved in towards the middle. This could be because most filters for this application (including this one) have no internal cage. Instead, they rely on the cage in the filter housing assembly itself. Maybe the diameter of the cage is slightly smaller, and the filter conforms down to it? Just curious. I've used this model filter before for a similar OCI, but I can't remember if it did this or not. I'm thinking that the threading on of the filter cap can sometimes twist these filters... However, pleats were still incredibly strong. I tried to pull back a few to get a look inside, and I couldn't. Anyhow, enjoy:
