The fine wire plugs are pretty darn durable. Mine are
the Unison (now tempest) ones. I find that they're easier
to clean with the walnut chip blaster because without the
massive side electrodes, it's much easier to get down in
them to clean them. They run real well for me. For my
dollar, I'll go Tempest fine wire for sure. There's nothing
magical about the Champions, and in fact you're just
sticking with something older at that point when there is
"new improved" available. The resistors alone are a good
reason to switch.
FWIW, I did the same thing with oil filters. After buying
2 each of Champion, Kelly, and Tempest, I now only buy
Tempest oil filters. The Kelly filters were just too
flimsy. The champion are higher price with lower
quality features.

Lorn,
Talked with Linda today. Still don't know the benefits of using fine
wire (Iridium) versus massive other than price. Champion massive are
$26.95 versus Tempest massive at $22.75. Champion fine wire (Iridium)
$89.95 versus Tempest fine wire (Iridum) at $49.50. These prices are
from Aircraft Spruce.
I like the idea of the center electrode and resistor being fused
together as one piece. That new design is found in both types of plugs
made by Tempest. The price difference between the two types of plugs
should be no factor since the Fine wire (Iridium) are supposed to last
1000 hours or more than the massive.
According to Linda, the platinum plugs are no longer being manufactured.
I have a call in to tech. Support at Champion but have not heard back
from them yet.

Art,
Iridium spark plugs will last for 2,000 hours. With the Champion plugs,
at 500 to 800 hours, you will either have to buy massive plugs to swap
the resisters or buy new iridium plugs. I went to the junk yard and
pulled good resisters out of used massive plugs. The Tempest plug
resisters will stay good for the life of the plug.
Other than the resisters, you will not be able to tell the difference
between the iridium plugs. Make sure that you don't get the older
platinum type.
To buy:
For good service with spark plugs call Linda Lou, Inc. in Memphis, Tn.
All Linda sells are plugs. She has replaced dropped plugs for me in the
past. Linda also gave me the number of a Champion rep. I will talk to
him in the near future and see if resisters or replacements are
available for the high resistance Champion plugs.
800-824-9912
Her prices for plugs are:
Tempest: $51.00
Champion: $89.95

you satisfied with them? Do you think they are better than Champion, and
why? Are you using the massive or fine wire? Help me make an informed
decision.

as their ad would suggest.
