Spark Plug Matching Chart: Everything You Need to Know

Spark plugs are essential for the proper functioning of your gasoline vehicle engine. They act as a catalyst because, thanks to their electrodes, they generate a spark, which leads to an explosion in the engine due to the combustion of a mixture of air and gasoline. Each spark plug has a different thermal degree, it is necessary to know the correspondence of the spark plugs by brand. In this article, we explain what the thermal grade of a spark plug is and provide a spark plug mapping table.

⚡ What does the thermal degree of a candle consist of?

Spark plugs are of different types a thread different depending on their thermal degree... They have two main missions: dissipate generated heat when burning between air and fuel and burn the remains is present in the system after the explosion. Thermal degree, often also called calorific valueshould be calculated according to the type of engine your vehicle is equipped with. Thus, it is with this temperature degree that it is possible to determine how the spark plugs will be used and, therefore, to select the appropriate models. However, if you install the wrong temperature spark plugs on the engine, two situations may arise:

• Candle with too high temperature : it will collapse very quickly and, melting, will merge with the engine piston. In this case, parts of the engine, such as the piston or valves, can be seriously damaged, which can even lead to complete damage to your car's engine;
• Candle with too low temperature : this will not be enough to ignite a mixture of air and gasoline in the combustion chamber. It will be difficult for you to start the car and you may notice excessive fuel consumption..

This spark plug mapping table allows you to find the equivalent in the brands NGK, Beru, Bosch and Champion using the reference number for that spark plug.

💸 What is the cost of replacing a spark plug?

The cost of replacing a spark plug may vary depending on the type of spark plug in your vehicle and the vehicle model. On average, it takes from 45 € and 60 € with parts included and work to replace one spark plug. If several candles need to be replaced, it will be necessary to multiply this price range.

Now you know how hot the spark plug is and what the differences are from one brand to another. If your car's spark plugs appear to be defective, you must intervene immediately to avoid damaging the engine or any other parts associated with the combustion chamber.
