The current motor experts are trying to give the satisfactory answer for how to and when to change spark plugs

How to change spark plugs?

Replacement of candles is recommended to be carried out in accordance with the manufacturer’s regulations and, of course, based on the variety of candles. To do this, insert a candle key and unscrew the candle. The main thing is that there is no o-ring left in the candle well, which should be located on the base of the candle.

When to change spark plugs?

If ordinary nickel candles have a resource of 20 thousand km, then iridium ones easily “nourish” up to 100 thousand km – this is about five years of operation.

It is important to consider that the following factors affect the performance and service life of spark plugs: the condition of the power unit, driving style and fuel quality. Drivers are advised to check the spark plugs at each MOT.

This will help keep the engine running properly and also avoid major repairs. A lot can be said by the condition of the spark plug – both about the state of the engine itself (whether there is oil consumption), or about the state of the power supply system. Diagnostics will allow timely maintenance and avoid costly car repairs.

Spark plugs can be removed both on a warm and cold engine. There are no temperature recommendations from any manufacturer.

What rules must be observed when replacing?

When replacing spark plugs, it is important to follow the manufacturer’s recommended tightening torque. Compliance with the tightening torque is possible only with the use of a special tool – a torque wrench. Failure to tighten the torque, as a rule, leads to damage to the candle itself and a reduction in its service life. It can also lead to damage to the components of the ignition system and even serious engine damage.
