I know this has been discussed before but I can't for the life of me find the thread it was on. Is there anything wrong with running BPR6ES in Zs?

Thanks

No - I believe that's the spark plug of choice.

Take your pick on threads: Google

The very short, very specific answer is no. Nissan used those plugs in some of the Z engines, but not all. They added the plug numbers to the Engine Tuneup chapter in the mid-70's if you have a certain engine in mind.
