[Roadsters] spark plugs--revisited

Now how does EI factor into this?  I know the gap is larger.  I have the BP6EY
(Vpower if that makes a difference) plugs on my car with a .040 gap.  Should I
go with a hotter or colder plug in my SU U20?

Short answer:
The BP5ES is one step hotter, and the BP7ES is one step colder, than the
recommended plug, BP6ES.
