Spark Plugs

[allmotorbeast]

whats the difference with ngk standard plugs and ngk v power plugs? they cost the same, but which on is better?

the standard plugs the copper electrode is flat, the V-power the electrode has a v looking notch in them.
this provides a sharper edge. This helps lower the amount of energy required to initiate the spark. I don't know the 100% technical reason, but sparks occur on the sharp edges of the plug.
