This is REALLY interesting!!! The procedure is this. Dislocate the front motor mounts. Then, using, a strap, rotate the engine towards you until you can gain access. It is really cool to watch done. I hope you have the good sense to be using a higher tech spark plug, like a Bosch Fusion, or Nippondenso Twin Tip plug. These will give better fuel mileage and power than the factory installed plugs. Also, vital sensors will last longer over time. You will save $$$$!!
