Best spark plugs for '92 SC DOHC - HELP!
-- Does it matter if the plugs are generic or for the model?
-- Is it good to upgrade to platinum or not (I'm getting different answers at the store.)?
-- Is it best to stay with ACDelco brand that GM used originally. (My last car cared about the brand.)
What are the best choice plugs to get? Napa has standard ACDelco 41-627 for $3.00 specific for these cars. Advance has a generic version of it, ACDelco 41-629 for lots of cars for $2.00. NAPA has platinum ACDelcos that will fit 41-808.
Does anyone have any experience to offer in general or specific to these plugs? I'll like to do it on my day off tomorrow, went to get the parts today...
Thanks so much!
