A spark plug is a device in the engine of a motor vehicle, which produces electric sparks to make the petrol burn.

A spark plug is threaded into the cylinder of an internal-combustion engine to ignite the fuel mixture by producing timed sparks between electrodes.

There are two types of spark plugs: copper tip plugs, which last 48,000 kms, and platinum and iridium tip plugs, which have a life expectancy of about 160,000 kms.

Common signs of faulty spark plugs include slow acceleration, loss of power, poor fuel economy, engine misfires, and difficulty starting the car. Just like oil can cause a spark plug to go bad, so can carbon build up. … A cracked distributor case, dirty fuel injectors, improper fuel/air mixture, clogged air filter element, to name a few can cause carbon to build up on spark plugs and quickly cause spark plug problems.
Spark plugs should be changed if you notice your vehicle with symptoms such as Rattling, pinging or “knock”-like noises. When spark plugs begin to misfire, you may notice unusual noises from the force of the pistons and combustion not working properly. Your vehicle may be hard vehicle start, reduced performance, and poor fuel economy.
