I seldom had complete failure of Champion plugs, only once where the
insulator desintegrated, causing some nasty damage in a Renault, but the
cause was unclear.
They do seem to foul up in slow traffic and wear faster than other
brands I have used, NGK, Bosch and Denso. I never used fancy plugs with
multi electrodes etc.
I still use the Champions though as they are dirt cheap and easily
available in the grade I want. I have always replaced them every year
(5.000mls) or earlier if they fouled in slow traffic. I always carry a
spare set.
For my day to day Subaru I have the dealer to worry about them, I
believe they are NGK. They are changed every 40.000mls or so.
