Spark plug is a component that has an important role in a motor vehicle, ie as the spearhead of combustion in the combustion chamber that will produce power that can move the piston.
Without this spark plug it is impossible for a car engine to power up and work properly (except electric cars). In the automotive world there is a spark plug called iridium spark plugs. This spark plug is actually the same as normal spark plugs in general, and the difference between the two is the usual spark plugs using ordinary electrodes, then in this iridium spark plug using iridium as the tip of the electrodes.
In general, this type of iridium spark plug has a pointed electrode tip which aims to keep the sparks focused and stable so that the combustion process is more efficient and fuel efficient although not 100% efficient. In addition, this iridium material also has a lower resistance or resistance so that flame sparks are more stable than normal spark plugs in general.
In addition, this type of iridium spark plug has a lifespan that is much longer and durable of course when compared with the usual spark plugs non iridium. If ordinary spark plugs should be replaced every 20,000km, the iridium spark plug is able to survive until the distance along the 100,000km.
But in addition to these advantages, the price offered from this type of iridium spark plug is more expensive, if the spark plugs usually cost between Rp. 25,000 to Rp. 35.000, then this iridium spark can range in price Rp. 100.000 and above for motor and Rp. 200,000 and above for car spark plugs.
