NGK spark plug grade: NGK double iridium or NGK iridium platinum which is better

NGK Double Iridium and NGK Iridium Platinum have their own advantages and disadvantages, and you can choose the spark plug suitable for your car based on their characteristics.

The center electrode and side electrodes of NGK double iridium gold are made of iridium. Due to the characteristics of high hardness, high corrosion resistance and high melting point, the service life of NGK double iridium spark plugs is the longest, up to ten. Million kilometers.And iridium is the most corrosion-resistant and wear-resistant precious metal, soNGK dual iridium spark plugs can meet the needs of high-power engines, and can withstand high-temperature conditions, making the electrodes less likely to be melted and damaged.

NGK iridium platinum uses iridium in the center electrode, which improves the ignitability and improves the sensitivity of engine ignition, while the side electrode uses platinum spark plugs. Due to the lower cost of platinum, NGK iridium platinum spark plugs are compared to NGK double iridium spark plugs. It is relatively cheap, and the price/performance ratio is relatively high.

In addition to selecting the type and brand of spark plugs, the spark plugs must be maintained to extend their service life and reduce fuel consumption.

The maintenance of spark plugs generally requires regular inspection, regular replacement, and regular cleaning. When the NGK spark plug is used to reach 5000-10000 kilometers, it needs to be removed from the engine to observe whether there is any abnormal phenomenon. If you find carbon deposits in the spark plug, you can soak it in kerosene for a period of time, use a thin steel brush to gently scrub, remove the carbon deposits, and dry them with compressed air before using.
