Yes I also could not find any info except for a few images of oil change places being azaki dealers, from who knows when.
The air filter is packaged exactly like a leppon. Same font and stuff. Same plastic cover and the filter looks the same too.
The oil filter may be a copy, as it's very light and doesn't look good quality. Has a mediocre plastic covering the bottom and you can see this red paste/glue if you look through the center hole. Ill probably use the air filter, but not the oil.
I inquired about genuine, otherwise I've been using guard for the last 3 oil changes without issue. It's just the guard one is a bit smaller for my pajero than the factory size which is why I'm a bit concerned.
