1/2W dissipation on a sparking plug should be no problem. Supplying all
the 1/2W might be a pain, but it could be used to heat the garage. :-)
Plugs are accustomed to operating quite hot, and (IIRC) 1/2W resistors
aren't that large. Plugs have _lots_ of surface area for heat
dissipation - far more than 1/2W resistors.
Enjoy 2019's new project!
Donald.
