More research
The F3+1 plug is unique. It alone, with its 4 electrodes, combines double copper technology and sliding spark technology. |
|
|
|
More security.
The combination of the "main electrode" and "side electrodes" architecture helps cut pollutants emissions. |
|
|
|
More reliability
Combining the reliability of a main ground electrode with three smaller electrodes, the F3+1 easily overcomes potential fouling for a high quality combustion. |
|
|
|
More flexibility
The main electrode can be adjusted to perfectly suit all types of vehicle, old or recent models. |
|
|
|
More efficient in cold conditions
With its sliding spark technology, the F3+1 plug ensures better starts even in the lowest temperatures conditions. |
|
|
|
More efficient in hot conditions
The F3+1 plug optimizes combustion in the chamber to cut fuel consumption and emissions of pollutants. |
|
|
|
Longer life
The cooled electrodes wear more slowly, so plug performance remains stable in the long run. |
|
|
|
More protection
The plug's cooled electrodes delay the appearance of possible combustion problems, which can damage high-performance and heavy-duty engines. |
