Iridium Spark Plugs?
Im about to do a tune up on my 89 NA ive noticed a lot of guys on the forum say they run iridium plugs but on the horizontal pillar in front of my radiator there is a warning label from Toyota saying to only run platinum tipped plugs? I don't know much of the difference between the two im guessing its just a different type of tip. Will it not hurt to run iridium plugs? I just want to get the best materials to do my tune up.
