Don't get the platinum ones, use the Autolite 3923's and gap them around 32...

I agree with "GREASY"
that's the same plugs that I'm running on my 306 S/C and I gapped the plugs to .32 and it performs very well..For some reason I tried platinum spark plugs and the car ran like crap...So get autolite 3923...LMK
