When someone asked you, how do you start your car? Would you be able to answer this question? Perhaps you could, you'll simply answer you insert your car's key to the ignition slot and your car automatically revs up. This is true but this will not take place if your car's ignition system and its parts do not exist. The ignition key slot of your Subaru is actually one of the parts of your Subaru ignition system. The other components include the spark plug, spark plug wires, and the coil.

The ignition system of your car has to work in perfect timing with the rest of your car's engine. Its goal is to ignite the fuel at exactly the right time so that the expanding gases can do the maximum amount of work and be able to make the engine work. With the reliable components of your Subaru ignition system, this goal is attained. Now, it's time to go through the components that create the spark.

The ignition coil is the heart of your car's ignition system. Once current flows through the ignition coil, a strong magnetic field is developed. The collapse of this magnetic field to the secondary windings makes a high voltage when the current is shut off. This high voltage is then directed on the way to the spark plugs. The spark plug forces the electricity to arc across a gap. This electricity should be at a very high voltage so that it could travel across the gap in order to make a good spark.

The spark plug should have an insulated passageway for this high voltage to travel down to the electrode wherein it can leap the gap and from there, be conducted to the engine block and grounded. This is your Subaru spark plug wires come into play. Your Subaru spark plug wires carry this high-voltage electricity without leaking out. They are designed to hold 20,000 to over 50,000 volts. Because of this tough job, your Subaru spark plug wires are designed to be thick and durable.

Then again, the insulation will eventually give in to the elements and to the heat of the engine causing these cables to crack, dry out and break down. This factor would surely affect your Subaru spark plug wires ability to deliver the needed voltage to the spark plug. There is nothing you can do about it but to have your Subaru spark plug wires changed.
