2 electrode plug from beru, bmw uses a 2 electrode plug on the m50's so beru is providing the plug that bmw calls for. I would not thing its a fake based on the electrodes. You haven't yet stated whether it taps loudly in the morning when its missing until it warms up, that will tell alot about whether the problem i HVA related or something else

I don't think I have enough experience to tell if it taps loudly. But it seems to me that there is no difference in engine noise while its cold and warmed up.

I changed the plugs and put the old Denso ones back. When the engine is started at first, it idles smoother, but after about a minute idle becomes a little more rough (the same as Beru Ultra). Those old Denso plugs look very bad. Another thing, after reaching operating temperatures, engine starts pinging when I accelerate a little faster. When its cold it does not. I did not have this pinging with Beru plugs. Picture of the Beru plug, exactly the one that I currently have. Even the made in France text http://www.partsbase.nl/ShowImage.asp?ID=Z14
Below are images of the Beru plugs after they were taken from the engine. I think the gasket on the cylinder head needs replacing, as there was some oil (a drip or so) on the some of the sparks.

you have a vacum leak or something else causing the misfire not the hydraulic lifters. If oil is getting on top of the plugs from the valve cover seals then that will contribute to the problem as well.
