More Info:
Denso Iridium Power spark plugs feature a 0.4mm iridium center electrode and best demonstrate their performance improvement during acceleration. The world’s smallest center electrode and specially shaped ground electrode deliver maximum spark energy while withstanding temperatures greater than 4000 degrees F. 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.
To increase ignitability, the flame kernel produced by the spark must be able to grow unobstructed. Normally, this can be accomplished by widening the spark gap. However, this causes spark voltage to increase, which has the opposite effect. Iridium Power plugs use Denso’s patented U-Groove ground electrode to achieve maximum ignitability while minimizing required voltage.
These spark plugs are available for a wide range of specific applications, including cars, trucks, vans, ATVs, UTVs, scooters, street and off-road motorcycles, personal watercraft, and snowmobiles. Order the model designed for your vehicle.
Key features and benefits of Denso Iridium Power spark plugs include:
• Patented 360 degree laser-welding assembly process
• Unsurpassed center electrode durability
• Available for many performance and power sports applications
• Improved spark ignition for maximum combustion, even with lean air-fuel mixtures
