Car Spark Plugs

Welcome to High Quality Store Car Spark Plugs Collection



You've probably heard the word spark plugs before. However, anyone who is not car or technology-savvy, often no longer knows about the small but really not unimportant parts of the car. If they break then you often do not know what to do.

A few important information about spark plugs, what they are there for and whether or how you can change them yourself, you can read in this article.


What is a spark plug and what is it good for?

Without the spark plugs your car would not start. They ignite the mixture of gasoline and air, which is necessary to start the engine. After ignition, a steady explosion pressure is generated, which forms the basis for the drive. Each cylinder has its own spark plug.

To ignite the gasoline-air mixture, a spark is ignited on one or more ground electrodes. This is located at the thread of the spark plug. Inside is the necessary counterpart, the center electrode. The spark must jump from the ground to the center electrode to allow enough heat to develop. This heat prevails throughout the ride in the combustion chamber of the cylinder and has a practical side effect: The spark plug is automatically freed from the accumulating residues and thus does not wear out so quickly. A disadvantage: Due to the constant heat and sparking, other engine parts around it may wear faster.


Differences and thermal values

There are two types of spark plugs: those with a sealing ring and those without a sealing ring. In addition, depending on the type of engine, they have other features such as the pitch of the spark plug thread, the thread diameter, the length of the spark plug, the number of electrodes, the electrode material, and the calorific value.

The correct heat values ​​can be found in the manual of the car. The distance of the electrodes is fixed and can be determined with the help of the so-called Blattlehre. This is a measuring device made of narrow sheet metal parts, with which the width of the columns can be measured.

Precious metal spark plugs are particularly durable. A platinum spark plug can last up to 60,000 kilometers, twice as long as standard candles. Spark plugs containing iridium are even longer and longer in life. They are the highest state of the art, the change interval is about 100,000 kilometers.


Spark plug change: Is a trip to the workshop necessary?

Since the constant heat and sparking can cause wear of other engine parts, spark plugs are now used as small and easily replaceable parts. The fact that one or more spark plugs need to be replaced is relatively easy to notice: there are misfires, the car starts to jerk or a cylinder even stops completely. Both result in a difficult engine run and can even be dangerous because misfiring can get unburned fuel into the catalytic converter and destroy it. Make sure you pay attention to gasoline smell.

How often you change the spark plugs sometimes depends on your car and how new it is. If it is still in the warranty, then the prescribed replacement interval should be adhered to, because otherwise void any warranty claims. Can be taken out the change interval of the operating manual of the car; typical values ​​are for example 30,000 and 60,000 kilometers. An indicator can also be the color of the electrodes. An optimally functioning spark plug has light brown electrodes, while a light gray to whitish color indicates a poor gasoline-air mixture.

If you want to change your spark plugs yourself, you must make sure that the new spark plugs are of the same type as the previous ones. The thread should also be screwed in as straight as possible and not tilted. If the position of the spark plug is incorrect, it will not work properly and damage the engine. In addition, she must not be stuck because she needs room to expand in the heat. Otherwise, the cylinder head may be damaged.
