While replacing spark plugs on normal cars is a pretty simple task, it is more difficult on the Porsche 911 due to the engine's horizontally opposed design and placement. Unless you have some experience working on cars, the right tools, and patience, we recommend going to an independent Porsche mechanic for this service.
