Yes. on the back of the bottle, it still says "Made in Germany". On the front, it says "European formula".
As for the Duratec (or mazda MZR)'s DAMB thingy, it is on the noisy (on 5w20) side. And the only way to adjust valve clearance is to replace the bucket tappets, which requires to loosen the timing chain and remove the cam shaft......sigh. I do hope the GC 0w-30 can do a better job in quieting the DAMB.
The DAMB thingy is just the cam lobe directly push the bucket tappet which is mounted directly on top of the valve spring.
In regard to the KN filter, I don't know, I usually use MC 820S on my MPV, this is a good filter, cost about $4, it has the relief valve at the base end (filter meets engine). On the Mazda3, I used MC 910, and switched to WIX (NAPA)1215. The KN number is HP-1002, which is a tiny bit fatter and bit longer. The OE filter has paper endplates. go figure.
