Has anyone had the spark plugs out? Are they traditional plugs or duel ground electrode plugs. I saw in the owners manual that spark plug type are NGK CR8EK or Denso U24ETR. Under the Denso plug site it shows a duel electrode plug that is interchangeable if engine is designed for duel ground electrode plugs.
