FEATURES
and
BENEFITS
WIDER-BASE INSULATOR
Unique design provides a wider, easier
path to speed the transfer of heat.
THERMAL-BONDING
A specially developed compound
between the center electrode and the
insulator nose helps to move heat
through and away from the plug firing
end.
COPPER-NUCLEUS CENTER-
ELECTRODE
Pure copper inside the chrome-nickel
electrode transfers combustion heat
away rapidly.
LONGER INSULATOR NOSE
Can tolerate up to twice the amount of
combustion deposits before fouling.
EXCLUSIVE NICKEL-ALLOY
Rapidly transfers heat from firing end
of plug, protects the electrode core and
resists erosion and corrosive elements
of combustion.
