A spark plug is a vital element of your car’s ignition system. Its purpose is to ignite the air/fuel mixture in an internal combustion engine. The combustion begins when a spark moves between the two electrodes of the plug, hence the name.
A spark plug is composed of a central electrode and an insulated wire, both placed in an electrically isolated shell. The wire connects the plug with the output terminal of the elements of the ignition system: an ignition coil or magneto. The central electrode is usually the cathode of the spark plug. Nowadays, the central electrode is made using two metals: the interior is made of copper and the exterior is made of steel. The outer steel part heats almost immediately providing a fast and reliable engine start, and a steady functioning.
In order to increase the durability of the spark plug, Bosch uses alloys of steel and noble metals (such as tungsten, iridium, palladium, rhodium and platinum) to make the central electrode. This allows reduction of the effects of corrosion and electrochemical destruction. The usage of those metals also makes the central electrode thinner. This has a positive impact on the efficiency of the ignition of the air/fuel mixture.
A lifespan of a spark plug is somewhere between thirty and one hundred thousand kilometers. After that you have to replace it with a new one. It is a fast and simple process, but it is always better to buy a spark plug that lasts longer and is more reliable. Bosch spark plugs are produced using the best materials and a manufacturing process tested for decades. When you buy their production you make sure that your car will function properly for many years to come.
Don’t forget that replacing the spark plugs in time is one of the basic rules that every car owner should know.
The air injection system of a car provides air for proper fuel combustion. Therefore it needs an efficient cleaning method. That is why air filters exist. They entrap dust and debris present in the air before it enters the engine.
A dirty air filter creates a barrier that prevents the air from entering the combustion chamber in large enough quantities. That has a direct influence on your vehicle’s power and consequently, fuel consumption. The micro particles of the polluted air have an extremely negative effect on the electronic system that controls the air injection into the combustion chamber. This can damage the flow meter, and you will have to buy a new one. Those particles can also deteriorate the combustion chamber itself, leaving fissures on its interior walls. In that case you may even have to replace the entire engine.
Car manufacturers usually recommend replacing your air filter after 30-40 thousand kilometers. This would be accurate for ideal conditions. However, big amounts of dust in cities’ air, sudden temperature drops, low quality of the roadway, among many others, can reduce the lifetime of the air filter. So a more realistic figure would be around 10-15 thousand kilometers.
Remember that you have to replace the air filter before it gets so dirty that it starts to obstruct the air flow into the combustion chamber. Don’t buy cheap air filters to try to save some pennies. It is much better to opt for a high-quality filter that will protect your car’s engine well. JC Premium air filters can entrap up to 99.97% of harmful particles, offering more stable filtration efficiency than cheap air filters.
It is not difficult to replace the air filter yourself. The plastic frame where the filter should go is usually located in the upper part of the engine. Just open the hood, remove the old filter and place the new one in the plastic frame.
