Ignition Coil
- Forester, Impreza 2.5L, Legacy, Outback 2.5L & Outback Sport
Ignition coils are made integral with an ignitor. 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 ignitor supplies current to an ignition coil and the ignition coil supplies high-voltage current to a pair of spark plugs (No. 1 and No. 2 or No. 3 and No. 4) simultaneously.
- Impreza WRX 2.0L & Outback 3.0L
The engines use a direct ignition system with one ignition coil mounted for each cylinder (or spark plug). The secondary terminal of the ignition coil is in contact with the spark plug terminal nut. Since no spark plug cable is used, secondary voltage drop, leaks or other problems that are inherent in a system using spark plug cables do not occur. The result is high performance and high reliability.
