Chevrolet Repair: Spark plugs, lumana, gm cars

Question
I have A Z-34 Lumana ,V-6 2 door. What kind of spark plugs do I use. I have new ones ,but dose it matter what kind of plugs I use?
Because the one I have they were 4 my old 4door 1996 lumana.
Dose it matter what kind of spark plugs U use eney ways.

Answer
Hi Chris... there should be a tag under the hood that will tell you what plugs to use. as far as brand goes GM cars and trucks always run better on AC plugs.use only the plug part number that the car calls for as any change in heat range could affect how the engine operates... hope this helps
