Denso is printed on the side of the models I've used, but depending on part number the country of origin may differ.

do they have a good beta ratio? what is their ADBV material? b/c on the 4.0, it's mounted threaded end down. I know with wix/napa gold I've never had issues and they are a well built filter.
I don't know about the beta ratio, but I believe the filter pictures posted on this and other sites show a silicone ADBV. The engineers that designed your engine spec'd that filter for factory recommended OCI's. You can't go wrong with the factory filter for 5K, but if you're running extended OCI's, by all means run a top of the line replacement.
