You might think its common sense that a V8 engine should have eight (8) spark plugs, but this depends on the type of V8 motor. So in order to answer the question of how many spark plugs are in a V8 motor, it is important to figure out the kind of V8 motor in your vehicle.
However, it’s a given fact that ordinary V8 motors will have a total of eight spark plugs. That’s one per cylinder. The same goes for V6 motors or four-cylinder engines with six and four spark plugs, respectively.
But there are some V8 motors from European and American brands that utilize dual-ignition or twin-spark technology. If this is the case, a V8 motor will have more than eight spark plugs.
