"What is more important is to
have the clip on shield in place to keep off wind and road debris. Wind will
cool it down and dirt/rain can foul it."
Do you know where these can be acquired Dennis. I've looked high 'n low on
the internet
and no luck. I'm considering using spark plug shields as they are good to
1200 degrees
and would be better than nothing, I think. Trouble is since they are
fiberglass and a fabric
sheath, they could collect ice, unless the heat of the sensor would prevent
that?
