Interesting, but I never had a problem..... How about Iridiums? EIX plugs? I just checked mine these weekend and they were perfect...
AND S14DB Speaks the TROOF!!!

I am not sure (I doubt it) if this conributed, but next time go with a JIS spec plug.
The relevant part number is
BCPR7ES-11 (Stock number 1095)....they come gapped at 0.044 so you have to close that down a bit.
Also, the BKR7E is a v-power tip.
As far as I know, ALL of the V-power tip NGK plugs are ISO length....sucks....
