I managed to get an OE plug, a Bosch plug, and a Beru plug.

I tested them all with a multimeter, the Bosch and Beru were 1.3Ohm, the OE (Beru) was 1.1-1.2Ohm. In the vehicle all plugs test out to around 0.6Ohm IIRC, so some of this is the coating or whatever measurement issue Inhad I guess. I’m using a hood fluke meter.

The Bosch box says made in France, the Beru box says made in Italy. All three GPs say Germany on them.

Here’s a close of of the OE Beru GP vs the Beru branded GP.
