Mmmhhhmm. I am not sure I understand the question. Gap distances are mostly individual to each plug type (don't ask why, I wouldn't know the exact reason). The NGK iridiums are intended to be non adjustable anyway (as far as I recall).
Sorry, that was not very clear, was it? In the chart the electrode gap for an NGK BP7ES is shown as 0.55 to 0.65 mm. I was wondering whether that gap was also correct for the NGK BPR7EIX.
