Sparkplugs.. Urgent Question?

[Konrad]

Just wondering what plugs everyone was running? I went out and got a set of ngk BCPR6ES, but when i went to install them my old ones were BCPR7ES which isn't even on the ngk website. Does anyone know what the difference between them would be?? (they have the same thread, and i think the 7ES was originally gapped at 11mm but is at 8mm now, the 6ES seems to be 8mm standard).

On the ngk website they recommend a PFR5G-11 or BKR5EIX-11 (irridium) for my car - a 94 s1 r33 gts-t.

Do i have the wrong plugs?? the old ones and the ones i bought appear identical on the outside (so they definatley will fit).

Could someone help please??
