How and when to change spark plugs on gas

It is important to clearly understand that modern candle models with a good service life are not suitable for all HBOs, but only for systems starting from the 4th generation. Branded samples are expensive, but the part will need to be changed less often, which will positively affect the budget, as well as the performance of the car.

Inexperienced motorists often wonder how much to change spark plugs on gas and whether it is necessary to replace the igniter when switching from gasoline. Thanks to useful information, advice and recommendations from experts, each owner of the car will clearly highlight the important criteria, taking into account which it is possible to extend the life of the engine, as well as to avoid reducing the efficiency of the motor.

Do I need to change spark plugs when switching to gas?

Every second vehicle owner agrees to re-equip a car, which involves the installation of gas-balloon equipment, in order to save fuel. After several days of operation of the machine, you can notice the consequences of switching to another fuel, this is due to the fact that after the spark plug fires, the gas ignites, creating a higher temperature than a mixture of gasoline and air masses. Due to this distinctive feature of the process, igniters can cease to perform their main function as efficiently as possible. The engine will start to triple, stall at the most inopportune moment, and at the first or subsequent start, let the owner of the vehicle down.

In the case of changing the spark plug when switching to gas, experts advise choosing specially designed models for such systems. Among the main differences from samples that are designed for a gasoline engine, it is worth highlighting a high glow index, as well as an increased gap between the electrodes.

Why change spark plugs after installing gas

Problems with fuel ignition are fraught with serious consequences, if the spark-producing part does not cope with the main task, then the accumulated fuel will give a reverse “pop” during the next cycle. Such ignition can damage the air intake sensors, as well as the intake manifold, which is made of plastic and is fragile.

The unstable operation of the engine often stops when switching to gasoline, such moments will indicate the need to replace the igniter, experts do not advise ignoring the manifestations. An important argument proving the need to install suitable spark plugs after switching to gas will be the gap between the electrodes. The optimal indicator for LPG versions is 0.8-1.0 mm, and models with a distance of 0.4-0.7 mm have been developed for gasoline systems.

When and how often to change spark plugs on gas

In order not to be mistaken and to accurately determine the frequency of replacing the igniter after installing a new part in the engine cylinder when switching to gas, it is important to be guided by the mileage indicated by the manufacturer. Often this figure does not exceed 30 thousand km. Spark plug wear can be noticed by listening to the operation of the engine, as well as by monitoring fuel consumption, if the spark is weak, it will not be enough to ignite the gas, some of it will simply fly out into the exhaust pipe. Expensive copies will last much longer, we are talking about such models:

  • FR7DC/Chrome Nickel with copper rod has a gap of 0.9mm, the maximum mileage is 35000KM.
  • YR6DES/Silver excels with 0.7mm electrode spacing and 40000 mileage.
  • WR7DP/platinum with a gap of 0.8 mm will allow you to drive 60000 km without changing the igniter.

Tips and Tricks

Since ICEs on gas no longer surprise anyone, although a couple of decades ago such systems were considered very dangerous and were not popular, car owners with many years of experience have gained a lot of experience in replacing and operating candles in combination with this type of fuel. One of the important tips shared by motorists concerns the transition to gas. By immediately changing the igniters, you can start saving up to 7% of fuel, and parts worn out by gasoline will not lead to excesses with starting the engine in the cold season.

When choosing specialized models for the HBO system, it is important to determine the gap, it should be larger than that of similar gasoline models. At the same time, the potassium number rises, it is designated lpg, such products are able to withstand significant temperatures. The power of the motor, which often runs on both fuels, will only be increased by the installation of universal igniters, but the products are expensive.
