The stock (BMW LOGO) plugs in my 1994 530i are
NGK BKR6EKU, they have been working great so I will stick with them.
I had the same problem in my 1997 VW Jetta. I switched the plugs and it cleared right up
Also what about the NGK BKR6EK.
The reason I ask is because I have a pinging problem with my '95 525 touring when accelerating from a stop. I've de-carbed the engine and run several bottles of injector cleaner. It is getting better. One of the things I did however, when I first started getting the problem was change the plugs. It looked like they were still original (bought car at 45K and it now has 50K). I put the Bosh+4's in even though about 1/2 the people here don't like them.
Since the problem is getting better, I'm wondering now if the only remaining thing that could be causing detonation is the plugs themselves.
I've not yet had a chance to take the car on a good long trip since the pinging started. That may fix it by itself. Hopefully in a couple of weeks I'll be able to take it on a 200-300 mile trip.
