Iridium Spark Plugs

Are they worth it or should i stick with the regular AC-Delco's?

Stick to regular AC delcos in 1995 and older and the AC delco Plats in 1996+ 4.3L.

Crack kills man, lay off the rock.:lol2:

Plats would not help out the 1991.

Standard AC Delcos will work fine.

No need for expensive plugs when the regular model does the job perfectly.

alright i got you's just wondering
