Don't know if = anyone brought this up yet but Tornado Alley Turbos has
recently = issued an "mandatory" service bulletin on fine wire plugs.
Apparently = they are more prone to insulator cracks than the massives.
When the = insulation falls off they turn into "glow plugs" and can lead
to a = detonation event. I think George has documented this. Here's = the
SB:

FWIW, I did the = same thing with oil filters. After = buying

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
