How to change spark plugs properly

When changing spark plugs, it's all about the right moves. The most important thing is to use a torque wrench and apply the correct torque, which is indicated on the packaging of each spark plug. In fact, if the torque is exceeded, the spark plug can be damaged, with serious consequences for the engine. However, the right tool is not only important when tightening the spark plug, but also when removing the old one and inserting the new one, you can make a lot of mistakes. Bosch recommends using a magnetic or rubberized socket and extension for this purpose, which prevents the spark plug from falling into the shaft and possibly being damaged. Additionally, the rubber or magnetic insert ensures sufficient space between the tool and the spark plug. This is important to prevent lateral forces from acting on the spark plug, or it being pushed out by the attached tool. Bosch recommends that you no longer use a spark plug that has fallen down, as it could be damaged – the ceramic may have cracks that are not visible to the naked eye. Cleanliness when changing spark plugs is also important to avoid contamination of the combustion chamber. The specified replacement intervals of the vehicle manufacturers must be observed, as spark plugs wear out over time, which can be easily recognized by the burn-off of the electrodes.
