Question about 2003 Kia Optima
We know where the front 3 spark plugs are but cannot get to the back 3 that are underneath an engine cover. It is a 2003 Kia Optima
I'm fairly certain those motors require the upper intake manifold be removed to gain access to the rear spark plugs. You might be better off bringing it to a qualified technician as it gets fairly involved. If i remember correctly it's about a 2 hour job and requires a few gaskets.
