Eagle spark plugs are vital components of your Eagle vehicle. They provide a place for the hot electrical spark to ignite the air/fuel mixture inside the combustion chamber of the internal combustion engine. This ignition process is successfully done through the aid of high voltage current arcing across a gap on the spark plug. Spark plugs are typically made of a center electrode, an insulator, a metal casing shell, and a side electrode, which is also known as the ground electrode. The center electrode is a thick metal lying lengthwise within the plug that conducts electricity from the ignition cable hooked to the plug's one end to the electrode gap at the other end.

The upper and lower portions of the center electrode are both exposed while much of the portion is surrounded by the ceramic housing or the insulator. The insulator is basically a hexagon-shaped shell with threads that allow the spark plug installation into a tapped socket in the engine cylinder head. The side electrode is a short thick wire that is made of nickel alloy and is connected to the metal shell and at the same time extending towards the center electrode. Your vehicle's thermal characteristic is measured by its heat range. This is the measurement of how long it takes heat to be removed from the plug's tip, firing end and transferred to the engine cylinder head.

If the plug tip temperature is too cold, chances are the plug can foul out or fail. A pre-ignition on the contrary, will most likely take place if the plug temperature is extremely hot which can possibly burn the center electrode and damage the piston. Any trouble with your Eagle spark plugs is really something serious and the best recommended remedy is a replacement. Do not worry now because we have the best Eagle spark plugs for you.
