Spark Plugs

Spark plugs are key components to your engine's combustion process. They provide the spark to the mixture of fuel and oxygen brought into your engine through the air intake and fuel pump.

They are made of conductive metals like copper, nickel, or iridium that pull electricity from the battery to create the sparks that ignite the ratio of fuel and oxygen in your engine cylinders. They are capable of withstanding high heat for long periods of time, which is why they are coated in a ceramic shell.
