Chevrolet Tracker Iridium Plug

A spark plug is a mechanism to transmit electrical current from an ignition system to a spark-ignition engine combustion chamber to ignite the compressed fuel / air mixture through an electrical spark, thus maintaining the combustion pressure within the engine. Spark plug contains essential and other metals in the middle and side electrode. The metal channels the high voltage from the spark plug wire into the spark plug so it can fire through the small gap between the main electrode and the side electrode as it goes through. This is the critical spark this starts the process of combustion. Iridium spark plugs feature a fine wire centre electrode designed to better conduct electrical energy and to improve the efficiency of the firing cycle. The price for this precious metal is high. Usually iridium spark plugs are the most costly spark plug. Acceleration is increased when you turn to Iridium spark plugs. The throttle operation has a fast response and you can feel the difference compared to the original plug. Iridium spark plugs boost power output on the engine. During conditions like climbing hills, the extra power is noticeable, giving you a relaxed driving and touring experience. An Iridium spark plug's ultra-fine centre electrode ensures a fast ignition and enhances the starting characteristics of the engine. Such devices offer economic as well as environmental benefits. Iridium spark plugs boost power output on the engine. The idling is steady, and fuel economy is better. Since Iridium spark plugs ensure excellent ignition, it effectively burns the fuel.

A spark ignites fuel in the engine. This starts with the ignition coil, which converts the power of low voltage into extremely high voltage. This high voltage is transferred to the spark plug through the ignition cables, where a spark is produced which ignites the fuel of the engine and power the engine.

Electrical current flows from the battery to the induction coil, which raises the friction to spark the plugs. Spark Plugs are required to make a smooth fire. Each spark connector is connected to an ignition device. As the coil produces high voltage, electrical impulses pass through shielded plug wires from the ignition coil. Spark plugs need voltage from a lower voltage battery approaching 20,000 Volts. When the voltage reaches the dielectric strength of the gases, the gap at the firing end of the plug is sprung by a spark and the air / fuel mixture is ignited.

Iridium spark plugs are fitted onto the cylinder head of the engine.
