I know Alfa Romeo make a big deal about their Twin Spark engines, which have 2 spark plugs per cylinder to improve power / efficiency. I'm not sure why all manufacturers don't use it if it does indeed improve power and efficiency? Also another point is that they don't actually fire both spark plugs at the same time to avoid the flame heads meeting in the middle of the cylinder.

Anyone know how much these corona spark plugs are gonna cost? They look super sweet but expensive
