How often to change the car high-pressure wire

PacificAuto.com car high-pressure wire is recommended to be replaced once in 40,000-50,000 kilometers. Once the high pressure wire is broken or aging and not replaced in time, the energy value of the ignition will be drastically reduced, fuel consumption rises, power decreases or even cut off the fire.

There are single-core, three-core, four-core, and five-core wires, and the more cores there are, the lower the resistance and the higher the ignition strength, but the higher the price. There is also the well-known high-voltage electric fire wire using silicone technology, can withstand the temperature range is -40 to 220 degrees, high pressure can be up to 35KV. but the more cores, the greater the current through the high voltage wire, which requires the use of high-voltage wire packaging with better shielding materials, otherwise it will produce electromagnetic interference, interference to the car's stereo or car computer. Many people know that spark plugs are consumables and need to be replaced frequently, but for other parts of the ignition system such as high pressure wires, they are often overlooked, once the high pressure wire is damaged or aging and not replaced in time, the ignition energy value will be greatly reduced, fuel consumption increases, the power decreases or even cut off the fire, which is a huge damage to the engine with three-way catalytic is a fatal blow, so regular inspection and replacement of high pressure wires should be done. So regular inspection and replacement of high pressure wires is imperative.
