RE: spark plugs

I have been a LONG TIME user of the plain-old Bosch platinums.
Chevy Spark Plug

My question is, how big does the spark have to be to ignight the fuel/air mixture? Isn't a small spark the same as the spark from a +4? I think it might be just marketing spit and polish.

It looks pretty cool though. :)
