A far more serious problem from automotive RF is the effect it has on
heart pace makers. A neighbor of mine has had problems with auto and
motorcycle ignition RF on several occasions. BTW, here in Santa Clara
there is a $50 fine for the first offense resulting from a complaint.
A better short term solution (in my opinion) to a plug fouling problem
is to use higher heat range plugs. However, I would hang on to the
colder plugs for hot weather and long distance driving.
