those are ngk V-power plugs, the notch is normal and is there when new.  as
they wear the notch can move a little bit.

Subject: [DML] Part of the problem? (Ignition discovery)


My super-whamo-dyne, new ignition components arrived today. Just to
prep, I figured I'd break a few spark plugs loose and inspect them.
Bill and some other folks recommended this.

What I found was quite strange to me. The plugs looked exactly as I'd
expected, yellow-ish insulator with sooty, rich, black carbon on
everything except the tip of the electrode from un-burned fuel caused
by ignition mis-fire. They looked perfectly normal except the soot.

The exception? A perfect groove had been deeply burned into the
electrode of every single plug. (Not the hook part, the "male" part)
I know some plugs are "split-fire" with split electrodes but I did
NOT buy those. The groove is very deep on some of the plugs, almost
down to the insulator and not always cut -precisely- in the center.
