Also, how is the combustion event in a water cooled motor different then the combustion event in an air cooled motor?

In 2002 Boxsters went from single hole injectors to 4 hole, O2 sensors changed to the improved Bosch LSF, also non-return fuel supply. All this led to more accurate air/fuel ratio which makes plugs last longer. I was refering to how the air-cooled engines are a completely different design from the M96 engines requiring different service procedures.
