Spark plug location Saab 9.3

If it's a 4 cylinder, there is a plate across the top of the engine, held in place with 4 bolts, and with a wiring plug attached to it's side. This acts as a combination "distributer" and "spark plug" wiring. Remove the 4 bolts, and the plate will lift right off. It may resist a little bit, because attached to the bottom of it are the 4 "boots" that push on to the spark plugs. Once you take it off, the spark plugs are right there. Be sure to blow any dirt or crud away from them before removing them, so junk does not fall inside the cylinders when you have the spark plugs out.
