96 Riv SC 3.8: Should I stick with AC Delco or go for Autolite or NGK ?

autolite 104 or 605's depending on your mods

no mods done on the car. What store carries the Autolite brand ?

ac delco is good but get the copper plugs in delco name. the autolite coppers are just cheaper if you change them out often. both work well in our cars. ngk are better than delco's but cost more and you wont see any difference unless you race alot.

I like to stick with a cheaper iridium brand. AC Delco 41101 cost $ 15.00 CDN. Dont know about Autolite and where you can get them or price of NGK's
