Iridium platinum spark plug life, advantages and disadvantages of iridium platinum spark plug

The iridium platinum spark plug is to replace the materials of the center electrode and the side electrode of the ordinary spark plug with the precious metals iridium and platinum respectively to improve the ignition performance and service life of the spark plug.

The advantage of the iridium platinum spark plug is that it uses iridium and platinum instead of the original electrode material, improves the tip structure of the ignition section, stabilizes the ignition gap at about 0.05mm for a long time, stabilizes the ignition voltage and makes the engine work smoothly. And because of its tip discharge characteristics, it makes the engine run more smoothly at low speeds, and has a longer mission life than ordinary spark plugs.

The disadvantage of iridium-platinum spark plugs is that they use precious metals as electrode materials, which greatly increases the cost and increases the price of iridium-platinum spark plugs, making the price of iridium-platinum spark plugs several times that of ordinary spark plugs.

The service life of iridium platinum spark plugs is much longer than that of ordinary spark plugs. Generally speaking, the service life of ordinary spark plugs is about 30,000 kilometers. If it exceeds 30,000 kilometers, it needs to be checked whether it needs to be replaced. The iridium platinum spark plug has a service life of 60,000 to 100,000 kilometers, which is more than twice the service life of ordinary spark plugs. Compared with ordinary spark plugs, the ignition performance of the iridium platinum spark plug is also greatly improved, and it does not require frequent maintenance, which can save a lot of trouble. Therefore, if conditions permit, it is recommended that car owners use iridium platinum spark plugs.
