I always had issues when I used any plugs other than Bosch Iridium or Platinum. You can even try Bosch copper plugs if you find the right heat and size. They're usually cheaper and better, but don't last very long... like 10k miles.
Pros: cheaper and better
Cons: don't last long

Volkswagen

So the new set of plugs arrived, so switched out them along with new wires, since two broke during work (Magneti Marelli) and since I already tested and bought a new coil pack basically the whole ignition system's now revamped.
So far after more than two hours of driving, no problems, but Im really careful since I dont wan to find out Im wrong, but it feels ok.
The old plugs where NGK, and after pulling them, their resistance measured on average about 4 kohms.
I kept the previous set, which where Beru's and they measured ~1.4 kohms.
The new set is Bosch, and Im going to stay away from NGKs since I drive a little bit sporty, lasted less than two years, and (I think) 20'000 km.
Pros: no problems after revamp
Cons: NGKs lasted less
