champion N5 ?

["Evangelos G. Makris" <emakris@hol.gr>]

This probably applies more to Frogeye owners.
I cannot find Champion N5's here anywhere.
Could you suggest another brand/type of sparkplug
that may be a direct replacement and, perhaps,
easier to find? NGK, Bosch, other?

Someone suggested using Champion N7YC's because they
have the same thread (14mm) and depth (19mm) as
the N5's, I am not so sure about the remaining 
characteristics though.

Thank you
