By harnessing the power of Iridium, DENSO is suddenly able to shrink the surface area of the center electrode - the critical component of a spark plug. Unlike a typical platinum plug that has a 1.1mm diameter center electrode, DENSO Iridium Power plugs have the world's smallest center electrode measuring 0.4mm in diameter. This means that the voltage requirements are decreased while firing performance is greatly improved.

Title: Porsche Engine Upgrade: The Benefits of Iridium Power Spark Plugs
Enhanced Performance: Iridium power spark plugs offer improved ignition efficiency, resulting in better engine performance and power output. They ignite the air-fuel mixture more effectively, leading to smoother acceleration, increased fuel efficiency, and reduced emissions.
Durability: Iridium is one of the hardest metals known, making Iridium power spark plugs highly durable. They have a longer lifespan compared to standard spark plugs, reducing the frequency of replacement and maintenance costs.
Superior Ignition: The small electrode diameter of Iridium power spark plugs provides a concentrated electrical spark, ensuring reliable and consistent ignition in all driving conditions. This leads to better throttle response, smoother idling, and reduced misfires.
Fuel Economy: Due to their efficient combustion properties, Iridium power spark plugs can contribute to improved fuel economy. By optimizing the burning of the air-fuel mixture, they help maximize the energy output from each drop of fuel, resulting in increased mileage and savings at the pump.
Compatibility: Iridium power spark plugs are available as original equipment (OE) replacements or as aftermarket upgrades specifically designed for Porsche vehicles. They are engineered to meet the precise specifications and requirements of different Porsche models, ensuring a seamless fit and optimal performance.
When considering the purchase of Iridium power spark plugs for your Porsche, there are a few factors to keep in mind:
Compatibility: Ensure that the spark plugs are compatible with your specific Porsche model and engine type. It's essential to choose the correct plug heat range and electrode design to match your vehicle's requirements.
Quality and Brand: Opt for trusted and reputable brands, such as NGK, Bosch, or Denso, to ensure the highest quality and performance. Genuine OE spark plugs from Porsche or high-quality aftermarket alternatives are recommended.
Maintenance Schedule: Consider the recommended maintenance interval for spark plug replacement in your Porsche owner's manual. Upgrading to Iridium power spark plugs can extend the interval between replacements, saving you time and effort in the long run.
