hi,

Friend of mine installed some boush spark plugs and car drove like poo - poo... its been only like 2 weeks and he hasnt had time to change them out.

the car stalled and turned off on the hwy and when he removed the plugs they were gone! all fouled and eaten up.

he replaced them with iridium plugs but still the car wont start?

any ideas?

thanks,

Did he gap them before installing ? I find it is always good to go
with the dealership OEM brand on GM cars

AC delco iridiums are OEM, and 99% of these plugs are pre gapped.

Bocsh are not made for these hotter ignition systems and will burn up quickly.

Anti sieze is always a good idea on the plug threads. :thumbsup:
