A spark plug essentially ignites the compressed air-fuel mixture within the combustion chamber. Malfunctions in such an important piece of equipment can adversely affect the engine operation. Besides, a faulty spark plug can make it difficult for you to start the engine. So, check the spark plugs regularly and replace the defective ones.
