Status: In Stock
Condition: New
The patented DENSO Iridium Power Spark Plug is designed to deliver unsurpassed performance and increase overall power and acceleration. Employing a revolutionary new 360-degree laser-welding process, DENSO has created a spark plug unlike anything on the market today. For that extra burst of power when you need it most, you can count on DENSO to harness the power of iridium to dramatically increase firing performance. The result is maximum horsepower and torque. With this in mind, if your vehicle exhibits bad spark plug symptoms including slow acceleration, poor fuel economy, or engine misfires, consider DENSO for your performance spark plug replacement. Trust in the iridium-spark-plug pioneer to provide performance spark plugs that showcase unmatched functionality, reliability, and fitment. From extreme race conditions to the daily driver, the DENSO Iridium Power Spark Plug is the ultimate performance spark plug.
- IMPROVE ACCELERATION: the 0.4mm iridium center electrode delivers maximum spark energy while withstanding temperatures in excess of 4,000 degrees Fahrenheit. These features combine to achieve higher ignitability and require lower spark voltage than ever before. As a result, acceleration improves in comparison with normal plugs
- MAXIMIZE IGNITABILITY: the patented tapered-cut U-Groove ground electrode achieves maximum ignitability even with lean air-fuel mixtures while minimizing required voltage
- ENHANCE PERFORMANCE: the Iridium Power design with its 360-degree laser weld is designed for durability under the most extreme conditions. The iridium alloy is six times harder and eight times stronger than conventional platinum and can handle temperatures associated with high-performance ignition and special fuel systems including Corvette, Viper, and Harley-Davidson
- REDUCE MISFIRES: the DENSO Iridium Power Spark Plug has low-required voltage and high ignitability, resulting in fewer misfires. The outcome is a dramatic improvement in combustion and engine output
- OPT FOR FASTER STARTS: the DENSO Iridium Power Spark Plug has a smaller center electrode, which dramatically improves ignitability for more horsepower, faster and easier starts, fewer misfires under heavy loads, and better fuel efficiency
