For the gapping on these plugs, .8mm is the correct gap? I just realized that's just a hair bigger than a .7mm pencil lead, which is small in it's self. I only mention pencil lead because that is the only thing I know of that is measured that small. So the gap is supposed to be that tight? Short of spending $140 on a CD factory manual, is there a source for specs on these engines/cars?
