Spark plug Denso Iridium Power IU27D 5390 

Brand: DENSOItem number: 5390

Iridium Power - Zero defects, original quality and improved performance.
Features and Benefits
Higher efficiency
Higher power with an optimal combustion cycle
Significant Combustion Improvement: Iridium Power has a low voltage requirement and high flammability, resulting in fewer misfires and no spark, resulting in significant combustion improvement
Higher engine output: Significantly improved combustion results in increased engine performance
Higher power under various driving conditions
Iridium Power
Unique power: the power produced by the 0.4 mm electrode is only achieved with these spark plugs
Outperforms all other types of plugs: when using an iridium center electrode with a thin center with a diameter of 0.4 mm, we get higher power than with plugs with diameters of 0.8 mm and 2.5 mm
Improved dynamics and acceleration
High flammability: the world's only 0.4 mm iridium center electrode and specially shaped side electrodes ensure high flammability and low voltage requirements
Improved ignition: Iridium electrodes give better ignition at the high voltage required and provide less misfire when ignition is difficult
Faster Acceleration: Acceleration is much higher than with conventional plugs
Motorcycle Factory Tests Show Iridium Power Best Acceleration
Data: Comparison by the company
More efficient fuel consumption
Better combustion, less fuel consumption, less noise
Higher engine efficiency: excellent ignition with the unique 0.4mm Iridium Power thin electrode provides much more efficient engine operation
More efficient fuel consumption: Compared to conventional plugs (W20FS-U) Iridium Power (IWF22), according to test results, fuel consumption is reduced by about 5%
Motorcycle Factory Tests Show Reduced Fuel Consumption With Iridium Power Spark Plugs
For car owners who value:
Increase in efficiency. Iridium Power Iridium Plugs are designed to be low voltage and highly flammable to help reduce misfire and misfire while significantly improving combustion. This increases the efficiency of the engine.
Improved acceleration. Thanks to stable ignition, dynamic performance is significantly improved.
Increased power. A 0.4mm center electrode increases power in a wide variety of driving conditions.
Reduced fuel consumption. Even at idle speed, better performance is ensured with a simultaneous reduction in fuel consumption and less noise.
Service life: up to 60,000 km.
