If you are having trouble starting your car, this could be due to several problems with the spark plugs or spark wires. In this article, we will present 6 signs that you need a mechanic ASAP.
What do spark plugs and spark wires do?
Vehicle spark plugs, wires, and other high voltage components help provide the spark that causes internal combustion in a vehicle’s engine.
- Wires carry electricity from the ignition coil (or distributor) to the spark plugs.
- This, in turn, causes a spark which ignites the mixture of fuel and oxygen, causing the pistons (cylinders) to move.
- The pistons provide the power needed to move the wheels and move the vehicle.
Over time, unburned gases and oils create a buildup of carbon residue on your car’s spark plugs, which can reduce the performance of your engine and make starting more difficult.
How long do spark plugs and spark wires last ?
Spark plugs have a lifespan of between 45,000 km and 120000 KM, spark wires can last twice as long.
- Like other parts of your car, this period varies depending on how you drive and how the spark plugs and spark wires are taken care of.
- It’s a good idea to have it checked, cleaned, or changed as necessary as part of your vehicle’s regularly scheduled maintenance plan.
