A spark plug is a critical component that transfers electric current from the ignition system to the combustion chamber of an internal combustion engine. It generates a spark to ignite the air-fuel mixture, initiating the combustion process essential for starting and maintaining efficient engine operation.

The main types of spark plugs include hot spark plugs and cold spark plugs. Hot spark plugs have a higher heat range, designed to dissipate heat slowly and maintain a higher operating temperature. Materials used for spark plugs range from copper to iridium, platinum, and others. Spark plugs find applications across automotive, marine, aerospace, and other industries, and are distributed through channels such as original equipment manufacturers (OEMs) and the aftermarket.
