【PREMIUM IRIDIUM PERFORMANCE】

Our spark plugs feature a high-quality iridium center electrode that provides rapid ignition and powerful performance. The extremely fine electrode tip concentrates spark energy for superior ignitability, enabling faster starts and smoother acceleration. Designed with an embedded copper core, these plugs ensure excellent heat dissipation and high-intensity thermal resistance.

【EFFICIENCY & LONGEVITY】

Asign Iridium Spark Plugs are built to last, offering an economic service life of 40,000 to 60,000 kilometers—up to 4 times longer than ordinary spark plugs. By optimizing combustion efficiency, they help improve fuel economy and reduce exhaust emissions while remaining highly resistant to dirt and carbon fouling.
