Splitfire Performance Spark Plug 911 / 928 / 944 - Exclusive V Electrode

Description

The Split Fire Spark Plug utilizes the exclusive Split “V” electrode which provides better and more efficient combustion. This is due to the unique split design which allows the flame kernel to move through the gap in the center as well as around the side of the electrode.

The Split “V” design differs from other spark plugs in the shape of the side electrode where, what usually is a solid arm, the metal is in a “V” shape. The gains that this shape provide are that when the flame kernel is usually blocked and sent around the electrode, the “V” design allows the flame to travel through the gap in the center as well as around the sides. This allows the flame to reach the center of combustion quicker so that there is less unburnt fuel leaving the combustion chamber. Because of this, more of the fuel that is injected into the combustion chamber is converted into power.

Other design features of the plug include a rib free ceramic insulator which ensures a good seal to reduce the chance of spark flashovers. The center electrode is copper-cored to provide superior heat control and distribution, enabling the ability for greater heat range options.
