What sparks plugs does a 1986 Mazda pickup truck use?

Answer 1

I would suggest using the nippendenso brand this is by far the best for Mazda Trucks in my 23 years of owning mine.However finding that most auto stores do not carry this brand NGK is a good replacement brand sold at auto zone definitely.Auto craft is also fine.STAY away from any plantinum plug they run TOO hot for the aluminum head and very difficult to remove if used.Stick with the standard plug made by nippendenso or ngk they are the best two choices overall.I currently use the ngk brand since the denso brand is not available at auto zone,napa,advance auto parts, car quest at least in my area.Gap is 0.31
