The difference between Yijin spark plug and platinum spark plug

If spark plugs are distinguished according to the electrode material, there are 4 categories, namely nickel alloy spark plugs, iridium spark plugs, platinum spark plugs and iridium platinum spark plugs. Therefore, the Yijin spark plugs mentioned in today's title do not exist, but iridium. So what is the difference between iridium spark plugs and platinum spark plugs? Although both are rare metals, there are still many differences.

Melting point:

The melting point of iridium is higher than that of platinum, so the iridium spark plug can continue to maintain a stable ignition state under the continuous high temperature operation of the engine. Of course, the discharge performance is also quite good. But it is not to say that platinum spark plugs are lacking in this respect. Under normal circumstances, they also have a very good performance. It is just that the iridium spark plugs are more in pursuit of stable performance.

Hardness:

Iridium spark plugs are much stronger than platinum in terms of hardness, so naturally Iridium spark plugs are better in terms of durability. Of course, platinum spark plugs are not bad either. Under normal conditions, the general life span can be as high as 100,000 kilometers, so there is no need to worry too much about this.

In general, iridium spark plugs are indeed better than platinum spark plugs in all aspects, but the price is definitely more expensive. Therefore, the platinum spark plug is definitely better for the price/performance ratio, after all, it is already very good. If conditions permit and you want better stability, I believe that choosing platinum spark plugs will definitely not let you down.
