Spark Plugs

A spark plug is a key part of the ignition system, delivering the electrical current from the coil into the combustion chamber to ignite the air-fuel mixture. Choosing the right spark plug ensures proper performance, fuel efficiency, and emissions control. Options range from iridium spark plugs, valued for durability and power, to trusted NGK spark plugs used in many applications. For installation or replacement, tools like a spark plug socket or spark plug wrench are essential. Many drivers upgrade spark plugs and coils together for better ignition performance, often seeking the best spark plugs for their vehicle.
