Subaru Impreza WRX (2004) ignition coils are made integral with an igniter. The ignition system is of a dual-ignition-coil design, each coil causing two plugs to generate sparks simultaneously. In response to the signal from the ECM, the igniter supplies current to an and the supplies high-voltage current to a pair of spark plugs (#1 and #2 or #3 and #4) simultaneously. The following schematic illustrates the Subaru Impreza WRX Wiring Diagram.
