Denso Iridium Spark Plugs are a game - changer. They sport the world's tiniest center electrode, just 0.4mm in diameter. This design exposes most of the spark to the air/fuel mixture instead of the metal surface, resulting in a 0.5 increase in fuel burn over platinum plugs. That directly leads to better gas mileage. The 0.4mm tip doesn't obstruct the electrical current, meaning less voltage is needed to generate a spark. This allows the spark plug to perform well in extreme driving conditions, ensuring top - notch performance at all times. Iridium is incredibly tough, being 6 times harder, 8 times stronger, and able to withstand temperatures 1,200°F hotter than platinum. Denso uses laser welding to attach the Iridium tip to the nickel base, creating a 360° seal. This makes the electrode resistant to wear even in harsh conditions. On average, these spark plugs require 5,000 fewer volts to fire compared to conventional ones. With less power needed and combined with U - Groove technology, the use of Iridium alloy, the tapered cut, and the ultra - fine 0.4mm electrode, they boost horsepower across the dyno range.
Using Denso Iridium Spark Plugs is straightforward. First, make sure your engine is cool. Remove the old spark plugs using a spark plug socket. Carefully install the new Denso Iridium Spark Plugs, but don't over - tighten them. It's important to follow your vehicle's recommended torque settings. When driving, you'll notice improved performance right away. For maintenance, periodically check the spark plugs for any signs of wear or damage. While these plugs are very durable, in extreme conditions, it's a good idea to inspect them every few months. If you see excessive wear or if your engine starts to misfire, it might be time to replace the spark plugs. Also, always keep the spark plugs clean and dry to ensure they work at their best.
