Parts manual shows NGK D-7ES or Denso X-22ES
The Denso seems to now have a U at the end now shows as Denso X-22ES-U
The NGK looks as though it is obsolete - I have resistor caps so don't want NGK DR-7ES.
Green Spark Plug Co shows the Denso X-22ES-U at good price.
Can't find my old spark plugs - I've been using some used NGK D8EA plugs to keep debris out.
