Mazda CX-7 Iridium Plug

A spark plug is the electrical power supply mechanism from an ignition device into one of the spark-ignition engine combustion chambers to ignite the mixture of compressed fuel/air through the electrical spark and keep combustion pressure within the engine. In the middle and side electrodes, the Spark plug includes basic metals and other metals. The metal channels the high voltage from the spark plug wire through the small gap so that it can fire between the main electrode and the side electrode on the way. The cycle of combustion starts with a vital spark. Iridium spark plugs feature a fine electrode wire center designed to better drive electricity and to improve the fire cycle efficiency. Iridium spark plug is typically the most expensive spark plug. When you turn to the Iridium spark plug, acceleration is increased. The throttle cycle has a quick reaction to the initial plug and you will notice the difference. Spark plugs of Iridium boost the engine's power output. The extra strength is visible in conditions like climbing hills, giving you a comfortable driving and touring experience. An ultra-fine center electrode with Iridium spark plug ensures fast ignition and increases engine starting characteristics. Such devices have both economic and climatic advantages. The spark plugs of Iridium improve engine power output. Idlings are smooth and fuel efficiency is higher. Their fuel is efficiently combusted as the Iridium spark plugs ensure good ignition.

A spark on the engine ignites the gasoline. It starts with the ignition coil which converts extremely high voltage to low voltage. This high voltage is transmitted via the ignition cables to the spark plug where a spark is produced which ignites the engine fuel and drives the engine.

Electrical current flows from the battery to the induction coil, which increases the voltage needed to ignite the plugs. Spark plugs are required to make a smooth fire. Each spark plug has an ignition system attached. Once the coil is producing high voltage, electrical impulses pass via shielded plug wires from the ignition coil. Spark plugs allow voltage from a lower voltage battery that exceeds 20,000 Volts. When the voltage reaches the dielectric strength of the gases, a spark sparks the gap at the firing end of the plug and the mixture of air and fuel is ignited.

Iridium spark plugs are mounted into the cylinder head of the engine.
