NGKBPR7ES...will one fit all?

[Mistaspakles]

I just purchased some NGK BPR7ES plugs on ebay and just wanted to be sure. The auction said the BPR7ES's were for various motorcycles and a few cars like the older porche and mercedes. Anyway, are these the same plugs that we all use in our cars? Or are there different types of BPR7ES's? Are they not all the same standard size?

They're all the same.

You wanted 6s instead. 7s may foul.

But, the best source for decoding a maker's code is the maker:

Even with HIS mods, which include an FP Green and a pantload of other stuff? Surely he's running pretty high boost, which I thought called for 7s. Not trying to argue, just want to know the straight scoop.

Yes, 7's are what I need. Running 20-21psi.

No, my duh. I'd never suspected someone asking about plugs would have had any mods. My mistake.
