Adjustment tool for 14mm spark plugs
Spark plug adjustment tool for all 14 mm spark plugs with top electrodes
Item no. 99067
The ease of handling enables accurate adjustment of the electrode gap. With setting gauge for uniform adjustment of all spark plugs.
As a result of erosion of the spark plug electrodes during operation of the engine, the gap between the centre electrode and the ground electrode of the spark plugs steadily widens, and above a certain gap this can lead to misfirings as it is no longer possible to generate ignition sparks. Cleaning the spark plugs and readjusting the spark plug electrode gap can extend the service life of the spark plug up to its wear limit.
