Hey, with the 12As, are there any difference in the NGK Sparkplugs as far as having a trailing and leading Sparkplug? I know with 2nd gens, theyt have both a leading(marked as leading) sparkplug and a trailing(marked as trailing) plug, that you buy as 2 leading and 2 trailing... but the NGKs for the 12A had only on kind, just making sure im buying the right stuff. btw, just making sure, trailing is the top 2 plugs and leading is the bottom

Thanks and sorry if this has been awnsered a million times(I warned you!!!)
