Spark Plug

[tvnpe]

Hi Guys,

How many hours do you guys get out of your spark plug? On my 98 Challenger 1800, I get the most may 10 hours out of a set of new plugs. It foul up easily and it is black wet when it foul. Any suggestion would appreciated, thanks.

Heck I got over 40 out of my 1996 challenger I only changed them... well just for the heck of it. You might be using the wrong heat range plug or gaped improperly. Check the injector for proper adjustment I would do a compression test too.
