Spark plug wires —This picture is of the top of the engine. It shows the location of the spark plug wires, ignition coil which supplies the spark plugs with the electricity needed to produce a spark, and the location of the fuel injectors. This engine is a MFI, Multi Port Fuel Injection system which means there is a fuel injector for each cylinder unlike a TBI Throttle Body Injection system which uses one or two injectors to supply fuel to the cylinders.
