Bought them for years going back to when they were in black cans, then white cans. Never had any issues in any of my cars . Will use the new ones in my KIA but not my Honda for the new ST filter that fits my CR-v is way to small for my taste. Champ makes the new ones
In Walmart today; ST9018 Cartridge and box both say USA...bunch of other printed stuff on cartridge. M1 cartridge printing matched exactly in words and font style...$6 more! BTW, boxes on both were unsealed from factory. Both claim 10K.........
I've order several Bosch from Rock Auto to see how they work. They claim partially syn.
Champ makes almost all the regular filters now. Not sure about the cartridge ones.
Use with confidence, although I wouldn't run them for 10K. Usually 7K are my OCIs.

The box of my ST10358 cartridge claims "Protection up to 10000 MI." The filter itself looks almost exactly like another brand filter that was on the shelf just above it.
