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.\u003cbr\u003e\u003cbr\u003eTo 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.\u003cbr\u003e\u003cbr\u003eThese 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.
