Spark Plug DENSO Iridium Power IK20 (5304)

The DENSO Iridium Power IK20 (SKU 5304) is a high-performance spark plug engineered to maximize combustion efficiency. Its primary feature is an ultra-fine 0.4mm iridium center electrode, which reduces the required ignition voltage and significantly enhances spark productivity. The U-groove ground electrode allows for a larger flame kernel, minimizing quenching effects and heat loss. This plug is ideal for gasoline engines requiring a heat range of 20 and is widely compatible with vehicles from Toyota, Honda, Mitsubishi, and Audi. Utilizing IK20 ensures a more stable idle, improved throttle response, and better fuel economy. Its high thermal resistance and anti-corrosion plating guarantee a long service life even under extreme operating conditions.
