FEATURES AND BENEFITS
WIDE-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.
