pound 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 depos-

its before fouling.
